Remarks

When you create a delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. Unless you remove the delegate, the event handler is called whenever the event occurs. Multiple delegates can be added to handle an event. For more information about event-handler delegates, see Handling and Raising Events.
