How to Get a Value of a Property By Using its Name in C#

Posted by Code Maze | Jan 25, 2024 | 0

How to Get a Value of a Property By Using its Name in C#

In programming, there are scenarios where dynamically retrieving the value of a property by its name becomes necessary. This guide delves into the intricacies of how to get the value of a property by using its name in C# using reflection . Assuming we have a foundational understanding of C# and reflection, we’ll skip exhaustive explanations of basic concepts. We will set up a simple console application to demonstrate this useful capability in C#.

Let’s dive in.

Retrieve Property Value By Name

To start, let’s consider a simple Person class:

We define a Person class with public fields and a single private field. We aim to retrieve property values from an instance of this class dynamically.

To retrieve the value of a public property by its name, let’s create a utility method:

Become a patron at Patreon!

To start with, we define a generic utility method, which means it can return properties of any type. Initially, the method checks if the provided obj object is null. This step is crucial to avoid a NullReferenceException . After ensuring the object is not null, we attempt to retrieve the public property information using reflection with the GetProperty() method. If the property doesn’t exist, we promptly inform the caller and exit gracefully.

Furthermore, it’s important to ensure that the property’s type matches the expected type TType . We achieve this using the is not operator, which checks if the property value can be cast to type TType .

In addition, if the property value is null and the expected type TType is nullable, we handle this scenario correctly. In such a way we ensure that we gracefully manage null values. Finally, if all checks pass, the property value is cast to type TType and assigned to the output parameter, thereby completing the process.

Finally, to test this out, let’s create an instance of the type Person and use our utility method to retrieve the value of Age property:

We pass the person object and Age string as the property name and we log the result to the console.

Upon inspecting the console, we will observe:

Retrieved value: 18. 

Please note, that the provided TryGetPropertyValue() the method only works for public instance properties retrieval. So, instance and static private properties and protected properties will not be found . To make it work with instance and static private properties and protected properties,  we can add BindingFlags to the GetProperty() method call:

PropertyInfo? propertyInfo = typeof(TObj).GetProperty(propertyName, BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static);

Handling Edge Cases

There are cases like property renaming, removal, and changes in type that can pose significant hurdles when trying to retrieve values. We already handled those cases in our method, but let’s just explicitly mention those.

Property Rename or Removal

When we use reflection in C# to access properties, handling scenarios where a property gets renamed or removed is crucial. Let’s consider a situation where we attempt to retrieve a non-existent Address property using our utility method:

PropertyRetrieval.TryGetPropertyValue<string>(person, "Address", out var value);

When we run the program and inspect the console, we will observe:

Property 'Address' not found.

Changing Property Type

Handling changes in property types is crucial, so, let’s test out our utility method for a case where we try to retrieve a property with a wrong type:

PropertyRetrieval.TryGetPropertyValue<string>(person, "IsDeleted", out var value);

Here we attempt to retrieve the value of IsDeleted property as a string type, however, we know IsDeleted is a boolean.

Upon running the program and inspecting the console, we observe the message:

Property 'IsDeleted' is of type System.Boolean, got System.String.

In this guide, we have explored how to get the value of a property by using its name in C#, furthermore, we used a concise and pragmatic approach, moreover, we have considered edge cases and handled them with finesse.

Remember, reflection comes with performance considerations, and its usage should be reasonable. The provided utility method serves as a tool, ready to tackle dynamic property retrieval challenges.

C# Tutorial

C# examples, c# properties (get and set), properties and encapsulation.

Before we start to explain properties, you should have a basic understanding of " Encapsulation ".

  • declare fields/variables as private
  • provide public get and set methods, through properties , to access and update the value of a private field

You learned from the previous chapter that private variables can only be accessed within the same class (an outside class has no access to it). However, sometimes we need to access them - and it can be done with properties.

A property is like a combination of a variable and a method, and it has two methods: a get and a set method:

Example explained

The Name property is associated with the name field. It is a good practice to use the same name for both the property and the private field, but with an uppercase first letter.

The get method returns the value of the variable name .

The set method assigns a value to the name variable. The value keyword represents the value we assign to the property.

If you don't fully understand it, take a look at the example below.

Now we can use the Name property to access and update the private field of the Person class:

The output will be:

Automatic Properties (Short Hand)

C# also provides a way to use short-hand / automatic properties, where you do not have to define the field for the property, and you only have to write get; and set; inside the property.

The following example will produce the same result as the example above. The only difference is that there is less code:

Using automatic properties:

Why Encapsulation?

  • Better control of class members (reduce the possibility of yourself (or others) to mess up the code)
  • Fields can be made read-only (if you only use the get method), or write-only (if you only use the set method)
  • Flexible: the programmer can change one part of the code without affecting other parts
  • Increased security of data

C# Property

last modified January 31, 2024

In this article we show how to work with properties in C#.

A property is a member that provides a flexible mechanism to read, write, or compute the value of a private field.

Properties use accessors through which the values of the private fields can be read, written or manipulated. Property reads and writes are translated to get and set method calls. Properties shield the data from the outside world while having a convenient field access.

A get property accessor is used to return the property value, and a set property accessor is used to assign a new value. The init property accessor is used to assign a new value only during object construction. The value keyword is used to define the value that is assigned by the set or init accessor.

Properties can be read-write (they have both a get and a set accessor), read-only (they have only a get accessor), or write-only (they have only a set accessor).

C# Property with backing field

The following example uses a property with a backing field.

We have the Name property with the _name backing field.

We create an instance of the User class. We access the member field using the field notation.

We have a property that is called Name . It looks like a regular method declaration. The difference is that it has specific accessors called get and set .

The get property accessor is used to return the property value and the set accessor is used to assign a new value. The value keyword is used to define the value being assigned by the set accessor.

C# read-only property

To create a read-only property, we omit the set accessor and provide only the get accessor in the implementation.

In the example, we have read-only properties. Once initialized in the constructor, they cannot be modified.

We make the property read-only by providing a get accessor only.

C# auto-implemented properties

C# has auto-implemented or automatic properties. With automatic properties, the compiler transparently provides the backing fields for us.

This code is much shorter. We have a User class in which we have two properties: Name and Occupation .

We normally use the properties as usual.

Here we have two automatic properties. There is no implementation of the accessors and there are no member fields. The compiler will do the rest for us.

C# init-only property

The init keyword is used to create init-only properties; these properties can be initialized only during object construction.

We define two init-only properties; they are initialized at the object construction. Later, they become immutable.

We use the primary constructor. It gives us two parameters: name and occupation . They are later used to initialize properties.

The init-only properties are created with the init keyword.

C# required properties

The required keyword is used to force the clien to implement the property.

We must use object initializers to create an object with a required property.

C# expression body definitions

Properties can be simplified with expression body definitions. Expression body definitions consist of the => symbol followed by the expression to assign to or retrieve from the property.

In the example, we use the expression body definitions to define properties for the User class.

Other notes

We can mark properties with access modifiers like public , private or protected . Properties can be also static , abstract , virtual and sealed . Their usage is identical to regular methods.

In the preceding example, we define a virtual property and override it in the Derived class.

The Name property is marked with the virtual keyword.

We are hiding a member in the Derived class. To suppress the compiler warning, we use the new keyword.

And here we override the Name property of the Base class.

C# Property

Summary : in this tutorial, you’ll about the C# property and how to use the properties effectively.

Introduction to the C# property

By definition, a property is a member of a class that provides a flexible way to read, write, or compute the value of a private field.

For example, the following defines the class Person with three private fields firstName , lastName , and age :

To assign values to and read values from these private fields, you use properties. The following shows how to add three properties to the Person class:

In this example, we declare a property like a field with a get and set blocks. The get and set are called the property accessors.

When you read from a property, the get accessor executes. And when you assign a value to a property, the set accessor executes. For example:

In this example:

  • First, create an instance of the Person class.
  • Second, assign the values to the FirstName and LastName properties.
  • Third, read values from the FirstName and LastName properties.

Using C# property for data validation

Since a property provides a central place to assign a value to a private field, you can validate the data and throw an exception if the data is not valid.

Suppose you want to implement the following validation rules:

  • The first name and last name are not null or empty
  • The age is between 1 and 150

To do that, you can add the validation logic to the set accessors of the properties as shown in the following example:

The following program causes an exception because the age is out of the valid range (1-150)

C# computed property

To create a computed property, you can implement the get accessor. For example, you can create a FullName property that returns the concatenation of the first name and last name:

And you can read from the FullName property:

If you attempt to assign a value to the FullName property, you’ll get a compilation error. For example:

C# auto-implemented properties

If you have a property that requires no additional logic in the set or get accessors, you can use an auto-implemented property.

The following example defines the Skill class that has two private fields name and rating , and the corresponding properties:

Since the accessors of the properties have no additional logic besides reading from and writing to private fields, you can use auto-implemented properties like this:

When the C# compiler encounters an auto-implemented property, it creates a private, anonymous field that can be accessed through the set and get accessors.

As you can see, the auto-implemented properties make the code more concise in this case.

In C# 9 or later, you can init an auto-implemented property like this:

In this example, we initialize the Rating property so that its value is one when you create a new instance of the Skill class.

  • A property is a member of a class that provides a flexible way to read, write, or compute the value of a private field.
  • A property contains get and/or set accessors.
  • The get accessor executes when you read the value from the property while the set accessor executes when you assign a value to the property.
  • Use auto-implemented property if the get and set accessors have no additional logic to make the code more concise.

Creating Property Set Expression Trees In A Developer Friendly Way

c# assign property value by name

The way I did it was not very developer friendly. It involved explicitly creating the necessary expressions because the compiler won’t generate expression trees with property or field set expressions.

Recently, someone contacted me to help develop some kind of command pattern framework that used developer friendly lambdas to generate property set expression trees.

Simply put, given this entity class:

The person in question wanted to write code like this:

Where et is the expression tree that represents the property assignment.

So, if we can’t do this, let’s try the next best thing that is splitting retrieving the property information from retrieving the value to assign to the property:

And this is something that the compiler can handle.

The implementation of Set receives an expression to retrieve the property information from and another expression to retrieve the value to assign to the property:

The implementation of this method gets the property information from the body of the property get expression ( propertyGetExpression ) and the value expression ( valueExpression ) to build an assign expression and builds a lambda expression using the same parameter of the property get expression as its parameter:

And now, we can use the expression to translate to another context or just compile and use it:

It can even support closures:

Not so useful in the intended scenario (but still possible) is building an expression tree that receives the value to assign to the property as a parameter:

This new expression can be used like this:

The only caveat is that we need to be able to write code to read the property in order to write to it.

C# – Using reflection to get properties

You can get a list of a type’s properties using reflection, like this:

Note: If you have an object, use movie.GetType().GetProperties() instead.

This outputs the following:

When you use GetProperties(), it returns a list of PropertyInfo objects. This gives you access the property’s definition (name, type, etc…) and allows you to get and modify its value.

In this article, I’ll show examples of using reflection to look for and use properties.

Table of Contents

Get and modify property values

You can use PropertyInfo.GetValue() / SetValue() to get and modify property values.

I’ll show examples of getting / modifying properties on the following Movie object:

Get property values

Use PropertyInfo.GetValue() to get a property’s value.

This example is getting all properties and their values:

Note: Notice the difference between reflecting a type’s properties vs reflecting an object’s properties (typeof(movie).GetProperties() vs movie.GetType().GetProperties()).

This outputs the property names and values:

Modify property values

Use PropertyInfo.SetValue() to modify a property’s value.

This example is modifying the Movie.Director property value:

This outputs the updated property value:

Problems to avoid

There are a few things to watch out for when using PropertyInfo.SetValue() / GetValue(). I’ll show examples in the sections below.

Set the right type

Movie.Id is an integer, and this is trying to set its value to a string:

This results in the following exception:

System.ArgumentException: Object of type ‘System.String’ cannot be converted to type ‘System.Int32’

To avoid this problem, convert the value to the right type. PropertyInfo.PropertyType tells you the right type, and you can use Convert.ChangeType() as a general purpose way to convert from one type to another:

Note: If you know specifically what type you are converting to, you can use the specific converter instead if you want (like Convert.ToInt32()), instead of the general purpose Convert.ChangeType().

Avoid modifying a read-only property

Let’s say Movie.BoxOfficeRevenue is read-only and you’re trying to modify it:

The behavior depends on how you defined the read-only property.

Surprisingly, you can modify the property’s value when it has a private setter (same behavior as a readonly field):

Note: This is technically not a read-only property, but you may want to avoid modifying its value from the outside, since declaring it with a private setter was probably done for a reason.

You can’t modify the value if the property doesn’t have a setter (a true read-only property):

You’ll get the following the exception:

System.ArgumentException: Property set method not found.

To avoid this, you can check PropertyInfo.SetMethod:

It’ll be null if there’s no setter, and SetMethod.IsPrivate will be true if it was declared with a private setter.

Check for nulls

GetProperty(name) returns null if it can’t find a property with the specified name, which can lead to NullReferenceException’s.

Let’s say BoxOfficeRevenue is defined as a readonly field:

And you mistakenly use GetProperty() to fetch this field :

Since BoxOfficeRevenue is a field , not a property , GetProperty() will return null. Since it’s trying to call .GetValue() on a null, it results in a NullReferenceException.

To avoid this problem, check if the PropertyInfo is null before using it.

Filter properties by definition (name, type, etc…)

There are two main ways to filter properties:

  • Pass in the BindingFlags enum flag parameter to control what GetProperties() looks for.
  • Filter the returned PropertyInfo objects by looking at its properties, such as PropertyInfo.PropertyType.

By default, GetProperties() returns all public instance and static properties of a type. When you pass in the BindingFlags parameter, it overrides the default behavior. So make sure to pass in ALL of the flags you want, including re-adding the default behavior if desired (ex: BindingFlags.Public | BindingFlags.Static | BindingFlags.Instance).

I’ll show a few filtering examples below.

Get a specific property by name

If you want a specific property by name, use GetProperty() instead of GetProperties().

This outputs:

By default, GetProperty() does a case sensitive search. You can do a case insensitive search like this by using BindingFlags.IgnoreCase, like this:

This matched “releasedOn” with the ReleasedOn property and output:

Get all private properties

Let’s say you want to get the following private instance properties:

To get these properties, use GetProperties() with these BindingFlags:

This outputs the two private properties:

Get all properties with a specific type

Let’s say you want to get all DateTime properties.

To do that, filter by PropertyInfo.PropertyType in a Where():

Get all properties that have a setter

Let’s say you want to modify property values, so you only want to get properties that have a setter. For example, you want to filter out the following read-only property:

To exclude read-only properties, filter by PropertyInfo.SetMethod in a Where():

This outputs all of the properties that have a setter:

Get properties that have an attribute

You can use PropertyInfo.GetCustomAttribute<T>() to check if properties have an attribute.

For example, let’s say you have the following two properties that have the [Required] attribute:

Note: [Required] is one of many built-in model validation attributes .

Here’s how to filter out properties that don’t have the [Required] attribute:

How to use value objects in C#

Learn how you can use value objects in c# to improve the clarity, structure, and maintainability of your code..

Plastic, magnetic letters in compartmented boxes.

In the C# programming language, an object can be either a value type or a reference type. While a variable of a value type contains its value, a variable of a reference type contains a reference to an object, or a reference to an instance of the type.

The key distinction between a value type and a reference type is in the assignment semantics. Additionally, because a value type is always “copied by value,” when you pass a value type as a parameter to a method or assign it to a variable, the entire data is copied. By contrast, when you assign a reference type, only the reference is copied; both references point to the same object in the memory.

C# also lets us create what’s called value objects, a special type of object used in domain-driven design that allows us to articulate domain concepts simply, clearly, and concisely. In this article we will examine value objects, discuss their benefits, and illustrate how we can use them in C#.

Create a console application project in Visual Studio

First off, let’s create a .NET Core console application project in Visual Studio. Assuming Visual Studio 2022 is installed in your system, follow the steps outlined below to create a new .NET core console application project.

  • Launch the Visual Studio IDE.
  • Click on “Create new project.”
  • In the “Create new project” window, select “Console App (.NET Core)” from the list of templates displayed.
  • Click Next.
  • In the “Configure your new project” window, specify the name and location for the new project.
  • In the “Additional information” window, choose “.NET 8.0 (Long Term Support)” as the framework version you want to use.
  • Leave the “Do not use top-level statements” and the “Enable native AOT publish” check boxes unchecked.
  • Click Create.

We’ll use this .NET 8 console application project to work with value objects in the subsequent sections of this article.

What are value objects in C#?

In the C# language, a value object is defined as an object that can be identified only by the state of its properties. Value objects represent a descriptive aspect of a domain without having an identity. In other words, value objects represent elements of the design that we care about only in terms of their contents, not their identities.

In domain-driven design (DDD), the value object pattern represents objects without identity and supports equality based on their attributes. It should be noted here that contrary to value objects, entity objects have distinct identities. Unlike entity objects, which are defined by their identity and have mutable state, value objects are defined by their attributes and are immutable.

Immutability means you cannot change a value object once it has been created; any operations performed on value objects will create a new instance instead. The immutability of value objects has important performance benefits. Because two value objects are considered equal if they contain identical values, even if they might be different objects, they become interchangeable. In other words, immutability enables object reuse.

A value objects example in C#

Consider the following class named Address, which contains a few properties and an argument constructor.

You can create an instance of this class and assign values to its properties using the following code.

However, because the Address class here exposes public setters, you could easily change the values of its properties from outside the class. This violates one of the basic features of value objects, namely its support for immutability.

We can fix this by redesigning the Address class as shown below.

As you can see above, the properties of our new Address class contain private setters, which do not allow changes to the value of any of these properties from outside the class, thereby preserving immutability. If you execute this program, you will be greeted with the error shown in Figure 1 below.

Figure 1. Value objects are immutable.

You can also implement value objects using records in C#. To do this, you use the record keyword to define a record type that encapsulates data much the same way we did with the Author class earlier. The following code snippet shows how you can define a record type in C#.

Best practices for using value objects in C#

When working with value objects in C#, you should follow these best practices:

  • Implement proper equality checks based on value to prevent inconsistencies and errors.
  • Use value objects to represent concepts in the domain model only when you feel it is appropriate.
  • Use value objects judiciously because they have performance overheads.
  • Consider implementing validation logic within your value object constructor to enforce business rules and constraints when the value object is created.
  • Adhere to recommended patterns and naming conventions to ensure clarity, consistency, and readability in your value object implementations.

Value objects encapsulate primitive types and have two main properties, i.e., they do not have an identity and they are immutable. Value objects can simplify complex data structures by encapsulating related data into a single unit. This ensures data integrity, enforces strong typing, reduces errors, and improves the readability of the source code. You can take advantage of value objects to enhance the clarity and maintainability of your C# code by providing a more expressive representation of the domain concepts.

Typically, creating value objects in C# involves overriding equality comparison and implementing appropriate value-based semantics. A typical practice involves overriding the Equals() and GetHashCode() methods, and providing other operators for comparison. Typically, we use a base class that comprises these methods that all value object implementations should extend.

In the above example, I’ve provided a basic implementation of value objects in C#. In a future post here, I’ll explore how we can implement a value object base class and discuss more advanced concepts.

Auto-Implemented Properties (C# Programming Guide)

  • 17 contributors

Auto-implemented properties make property-declaration more concise when no additional logic is required in the property accessors. They also enable client code to create objects. When you declare a property as shown in the following example, the compiler creates a private, anonymous backing field that can only be accessed through the property's get and set accessors. init accessors can also be declared as auto-implemented properties.

The following example shows a simple class that has some auto-implemented properties:

You can't declare auto-implemented properties in interfaces. Auto-implemented properties declare a private instance backing field, and interfaces may not declare instance fields. Declaring a property in an interface without defining a body declares a property with accessors that must be implemented by each type that implements that interface.

You can initialize auto-implemented properties similarly to fields:

The class that is shown in the previous example is mutable. Client code can change the values in objects after creation. In complex classes that contain significant behavior (methods) as well as data, it's often necessary to have public properties. However, for small classes or structs that just encapsulate a set of values (data) and have little or no behaviors, you should use one of the following options for making the objects immutable:

  • Declare only a get accessor (immutable everywhere except the constructor).
  • Declare a get accessor and an init accessor (immutable everywhere except during object construction).
  • Declare the set accessor as private (immutable to consumers).

For more information, see How to implement a lightweight class with auto-implemented properties .

  • Use auto-implemented properties (style rule IDE0032)

    get { return _name; } set { _name = value; } } // Declare an Age property of type int: public int Age { get

  4. PropertyInfo.SetValue Method (System.Reflection)

    Assembly: System.Runtime.dll Sets the property value for a specified object. Overloads Expand table SetValue (Object, Object) Sets the property value of a specified object. C# public void SetValue (object? obj, object? value); Parameters obj Object The object whose property value will be set. value Object The new property value. Exceptions

  5. How to Get a Value of a Property By Using its Name in C#

    To retrieve the value of a public property by its name, let's create a utility method: Support Code Maze on Patreon to get rid of ads and get the best discounts on our products! public static bool TryGetPropertyValue<TType, TObj> (TObj obj, string propertyName, out TType? value) { value = default; if (obj is null) {

  6. c#

    To get the value of a property on targetObject: var value = targetObject.GetType ().GetProperty (vari).GetValue (targetObject, null); To get the value of a field it's similar: var value = targetObject.GetType ().GetField (vari).GetValue (targetObject, null); If the property/field is not public or it has been inherited from a base class, you ...

  7. C# Properties (Get and Set)

    The set method assigns a value to the name variable. The value keyword represents the value we assign to the property. If you don't fully understand it, take a look at the example below. Now we can use the Name property to access and update the private field of the Person class: Example class Person { private string name; // field

  8. C# Property

    u.Name = "Jane"; Console.WriteLine(u.Name); We create an instance of the User class. We access the member field using the field notation. public string? Name { ... } We have a property that is called Name.

  9. Assignment operators

    The assignment operator = assigns the value of its right-hand operand to a variable, a property, or an indexer element given by its left-hand operand. The result of an assignment expression is the value assigned to the left-hand operand.

  10. C# property

    First, create an instance of the Person class. Second, assign the values to the FirstName and LastName properties. Third, read values from the FirstName and LastName properties. Using C# property for data validation

  11. Dynamically set property value in a class (C#)

    Rarely needed as in C# object types and properties are known although there are rare occasions this may be needed when dealing with data received with a property name as type string and value of type object. Example Using the following class and enum. public class Settings { public string UserName { get; set; }

  12. c#

    public interface IPropertyAssignator<T> where T : class { void Assign (T target, string propertyName, object value); } /// <summary> /// Dynamically assigns values to properties of an object /// </summary> /// <typeparam name="T">Assignation's target type</typeparam> /// <remarks>This class is not thread safe.</remarks> public class DynamicPr...

    1 I have a List that I am iterating through. Inside the List<> are Argument classes which contain two properties 'PropertyName' and 'Value' What I need to do is iterate through the collection of Arguments and assign the Value of that Argument to the Property (with the same name as current Argument) of a different class. Example:

  14. C# Property

    Introduction. C# properties are members of a C# class that provide a flexible mechanism to read, write or compute the values of private fields, in other words, by using properties, we can access private fields and set their values. Properties in C# are always public data members. C# properties use get and set methods, also known as accessors to ...

  15. Properties

    In some cases, property get and set accessors just assign a value to or retrieve a value from a backing field without including any extra logic. By using auto-implemented properties, you can simplify your code while having the C# compiler transparently provide the backing field for you.

  16. Creating Property Set Expression Trees In A Developer Friendly Way

    The person in question wanted to write code like this: C#. var et = Set ( (Person p) => p.Name = "me" ); Where et is the expression tree that represents the property assignment. So, if we can't do this, let's try the next best thing that is splitting retrieving the property information from retrieving the value to assign to the property:

  17. c#

    Is there a way to refer to a property name with a variable? Scenario: Object A have public integer property X an Z, so... public void setProperty(int index, int value) { string property = ""; if (index == 1) { // set the property X with 'value' property = "X"; } else { // set the property Z with 'value' property = "Z"; }

  18. C#

    You can get a list of a type's properties using reflection, like this: Console.WriteLine(propertyInfo.Name); Code language: C# (cs) Note: If you have an object, use movie.GetType ().GetProperties () instead. When you use GetProperties (), it returns a list of PropertyInfo objects.

  19. Object and Collection Initializers

    In this article. C# lets you instantiate an object or collection and perform member assignments in a single statement. Object initializers. Object initializers let you assign values to any accessible fields or properties of an object at creation time without having to invoke a constructor followed by lines of assignment statements.

  20. How to use value objects in C#

    In the C# programming language, an object can be either a value type or a reference type. While a variable of a value type contains its value, a variable of a reference type contains a reference ...

    . . PropertName100 = "alex" I need to create an instance of RequestData and assign all the property values to each of the property names In this scenario, I need to do like this which will result in 100s of lines RequestData requestData = new RequestData (); requestData.PropertName1 = "Timothy" ; requestData.PropertName2 = "Rajan" ;

  22. Auto-Implemented Properties

    public string FirstName { get; set; } = "Jane"; The class that is shown in the previous example is mutable. Client code can change the values in objects after creation. In complex classes that contain significant behavior (methods) as well as data, it's often necessary to have public properties.
