 virtual void OnGiveFeedback(System::Windows::Forms::GiveFeedbackEventArgs ^ gfbevent);
protected virtual void OnGiveFeedback (System.Windows.Forms.GiveFeedbackEventArgs gfbevent);
abstract member OnGiveFeedback : System.Windows.Forms.GiveFeedbackEventArgs -> unit

Protected Overridable Sub OnGiveFeedback (gfbevent As GiveFeedbackEventArgs)

參數

gfbevent
GiveFeedbackEventArgs

GiveFeedbackEventArgs,其中包含事件資料。A GiveFeedbackEventArgs that contains the event data.

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.

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

當在衍生類別中覆寫 OnGiveFeedback(GiveFeedbackEventArgs) 時,請確定呼叫基底類別的 OnGiveFeedback(GiveFeedbackEventArgs) 方法,使已註冊的委派能接收到事件。When overriding OnGiveFeedback(GiveFeedbackEventArgs) in a derived class, be sure to call the base class's OnGiveFeedback(GiveFeedbackEventArgs) method so that registered delegates receive the event.
