C# Expression-bodied members

C# expression bodied members allows us to define members (property or method) definition in a single expression.

This expression is very concise and readable in nature.

We can use expression body definition with the following.

Method
Property Get

C# Expression-bodied members syntax

C# Expression-bodied method

It consists of a single expression. If method has a return type, expression must return similar type. Let’s see an example.

C# Expression-Bodied Method Example

 using System; namespace CSharpFeatures {     public class Student     {         private string Name { get; set; }         // Expression bodied method         public void ShowName() => Console.WriteLine(Name);         public static void Main()         {             Student student = new Student();             student.Name = “Peter John”;             student.ShowName();         }     } } 

Output

Peter John

C# Expression bodied Property Get

We can use expression body to implement get property. A single expression can be used to set a value for the property.

We should not use return statement in this property.

Let’s see an example, that implements expression body in get property.

C# Expression-Bodied Get Property Example

 using System; namespace CSharpFeatures {     public class ExpressionGet     {         // Expression bodied get property         private static string Name { get => “Tutoraspire”; } // Passing value using expression body         public static void Main()         {             Console.WriteLine(ExpressionGet.Name);         }     } } 

Output
