Multicast delegate is an extension of normal delegate. It helps you to point more than one method at a single moment of time.

In a windows application, we created a button on a form and on the button click, we want to invoke two methods (AlertMsg(), WarningMsg()). So the code is as follow:

\

```
public class Deligatedemo{    public Deligatedemo ()    {    }    // Declare a delegate public delegate void Notification(string msg);    public void Process(Notification handler)    {        if (handler != null)            handler("Alert  Message");        if (handler != null)            handler("Warning   Message");    }}  public class demoClass{    //This method will show alert message to user    public static void AlertMsg (string s)    {         MessageBox.Show(s);    }    //This method will show warning message to user    public static void WarningMsg(string s)    {         MessageBox.Show(s);     } } private void button1_Click(object sender, System.EventArgs e){     Deligatedemo dc = new Deligatedemo();    Deligatedemo. Notification notified = null;    notified+= new DeligateClass. Notification (AlertMsg);    notified+= new      DeligateClass. Notification (WarningMsg);    dc.Process(notified); }
```
