Introduction

In this post I'm going to explain about Anonymous Functions in C#

Anonymous functions

In C# 1.0 you can use a delegate and pass a function reference with an initializing delegate with a function name, but C# 2.0 introduced anonymous functions.

Anonymous function is a inline function or expression that a delegate is using.

Example

Creating an anonymous function as an inline block of code to be passed as a delegate parameter. Please see below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Anonymous
{
    class SimpleAnonymous
    {
        public delegate void delegateAnon();

        static void Main(string[] args)
        {
            delegateAnon obj = delegate() {
                Console.WriteLine( "Simple Anonymous");
            };

            obj();
        }
    }
}

Use of an anonymous function can reduce the lines of code. So, here in the program above you can see I just passed a block of code for a delegate parameter inside of creating a function anywhere else and passing the function name. The anonymous function uses the delegate keyword while delegate initialization writes a block of code. You can also pass a parameter for an anonymous function as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Anonymous
{
    class AnonymousParam
    {
        public delegate void delegateAnon( string Mesg);

        static void Main(string[] args)
        {
            delegateAnon obj = delegate(string Mesg) {
                Console.WriteLine(Mesg);
            };

            obj("AnonymousParam");
        }
    }
}

Conclusion

Guys hope I explain it peoperly.
