Delegate means function pointer.
There are two types of delegate
1-simple delegate
2-multicast delegate.

for simple ex:

private void Page_Load(object sender, System.EventArgs e)
{
Label2.Text= DoAction(new Action(Add)).ToString();
Response.Write ("<BR>");
Label3.Text= DoAction(new Action(Sub)).ToString();
//
// // Put user code to initialize the page here
}

static int DoAction(Action action)
{
return action(5,2);
}
public int Add(int n,int m)
{
return n+m;
}
public int Sub(int n,int m)
{
return n-m;
}
