例外狀況

備註

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊, 請參閱處理和引發事件For more information, see Handling and Raising Events.

OnInit 方法也允許衍生類別處理事件,而不用附加委派。The OnInit method also allows derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

在衍生OnInit(EventArgs)類別中覆寫時, 請務必呼叫基類OnInit(EventArgs)的方法, 讓已註冊的委派能接收事件。When overriding OnInit(EventArgs) in a derived class, be sure to call the base class' OnInit(EventArgs) method so that registered delegates receive the event.
