Delegates in C#
A delegate in C# is similar to a function pointer in C or C++.

A delegate is a type that references a method.
Once a delegate is assigned a method, it behaves exactly like that method.
The delegate method can be used like any other method, with parameters and a return value.

Syntax:
delegate result-type identifier ([parameters]);

where,
result-type: The result type, which matches the return type of the function.
identifier: The delegate name.
parameters: The Parameters, that the function takes.


An interesting and useful property of a delegate is that it does not know or care about the class of the object that it references.
Any object will do; all that matters is that the method's argument types and return type match the delegate's.
This makes delegates perfectly suited for "anonymous" invocation.

A sample delegate program:

using System;

namespace forgetCode
{
    delegate void Mydel(string s);

    class program
    {
        public static void method1(string a)
        {
            Console.WriteLine("Hi," + a);
        }

        public static void method2(string b)
        {
            Console.WriteLine("Hello," + b);
        }


        public static void Main()
        {

            Mydel a, b;

            a = new Mydel(method1);
            b = new Mydel(method2);
          

            a("Forget Code");
            b("Forget Code");
                      
        }
    }
}



Output:

Hi, Forget Code
Hello, Forget Code
