Delegate in C#

Delegate is always been a weird word for the C# starters. But actually it is same as function pointers in C++.

Here I am giving one line definition and a very small easy understandable sample here.

Delegate is a reference type variable which holds the reference for a method. The reference can be changed at run time.

Syntax:

delegate <return-type> <delegate-name>;

Ex program:

 // defining Delegate

public delegate int Calculation(int x);

Public Class Test

{

int n=10; m=10;

Public int AddNum(int a)

{

int n +=a;

return n;

}

Public int MulNum(int b)

{

Int m= m*n;

Return m;

}

Public string void args[]

{

//creating instance for delegate

Calculation acalc = new Calculation(AddNum);

Calculation bcalc = new Calculation(MulNum);

//passing values to the delegate

Console.WriteLine(The Added Value is {0}",acalc(25));

Console.WriteLine(The MultipliedValue is {0}",bcalc(10));

}

}

The result will be: 35 and 100.

Yes its the way it is working. Just do an example program and get the way out....
