C# Anonymous Functions

A function without a name is known as an anonymous function. Anonymous functions are of two types in C#:

• Lambda Expressions
• Anonymous Methods

C# Lambda Expressions:

An anonymous function used to create delegates is called lambda expressions in C#. To create local functions to be passed as an argument, a lambda expression can be used. Also, to write LINQ queries, the lambda expression is useful.

Syntax:

(input-parameters) => expression

Example:

using System;  
namespace LmbdaExpr 
{  
    class Example  
    {  
        delegate int Cube(int n);  
        static void Main(string[] args)  
        {  
            Cube GetCube = a => a * a * a;  
            int x = GetCube(10);    
            Console.WriteLine("Cube: "+ x);  
        }  
    }  
}

Output:

Explanation:

In the above example, we are displaying the use and behavior of the lambda expression in C#.

C# Anonymous Methods:

With the functionality the same as the lambda expression, the Anonymous method also allows the user to omit the parameter list.

Example:

using System;  
namespace AnymsMethd 
{  
    class Example  
    {  
        public delegate void AnymosFun();  
        static void Main(string[] args)  
        {  
            AnymosFun x = delegate () {  
                Console.WriteLine("Hello World!!");  
            };  
            x();  
        }  
    }  
}

Output:
