MULTICAST DELEGATES IN C#.NET WITH REAL TIME EXAMPLE..

delegates used to invoke one function. Multicasst delegate
is used to invoke mmore than one function
Say for example
This is our delegate
delegate void myDelegate (string s);

Weh ve two functions like
publc void sayHello(String Name)
{
//implementation goes here
}
public void sayHai(String Name)
{
//implementation goes here
}

If we want to invoke both of these functions
use like

myDelegate md= new myDelegate(sayHello);
md+=new myDelegate(sayHai);
