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 => "Javatpoint"; } // Passing value using expression body
        public static void Main()
        {
            Console.WriteLine(ExpressionGet.Name);
        }
    }
}

Output
