定義

參數

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.

OnItemAdded 方法也允許衍生類別處理事件,而不用附加委派。The OnItemAdded 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

當覆寫OnItemAdded(ToolStripItemEventArgs)衍生類別時,請務必呼叫基底類別OnItemAdded(ToolStripItemEventArgs)方法,讓已註冊的委派收到事件。When overriding OnItemAdded(ToolStripItemEventArgs) in a derived class, be sure to call the base class' OnItemAdded(ToolStripItemEventArgs) method so that registered delegates receive the event.
