Mulicast delegate is a delegate that can have more than one element in its invocation list.
Example
public delegate void MultiDelegate(int x,int y);
private class Operator{
public void Add(int x, int y)
{
MessageBox.Show ("The sum is: " + (x + y));
}
public void Sub(int x, int y)
{
MessageBox.Show("The sub is: " + (x - y));
}
}
MultiDelegate ptr=null;
//add more than one function called multicast delegate.ptr += new MultiDelegate(obj.Add);
ptr += new MultiDelegate(obj.Sub);
ptr(50, 10);
