Delegates are used to declare, instantiate, and invoke a function with a specific signature. For event handling, a delegate maintains a list of event handlers that are registered to receive the event. When the event is raised, the delegate invokes all of the registered event handlers in its list. Therefore, the delegate must maintain a list of the registered event handlers for the event.
