備註

OnVerifyingAnswer該方法會在使用者對密碼恢復確認問題的答案送交會員提供者驗證前被呼叫。 預設實作會提升事件。VerifyingAnswer

發起事件會透過代理呼叫事件處理者。 欲了解更多資訊，請參閱 處理與提升事件。

此 OnVerifyingAnswer 方法也允許衍生類別在不附加代理的情況下處理事件。 這是在衍生類別中處理事件的首選技術。

給繼承者的注意事項

在導出類別中覆寫 OnVerifyingAnswer(LoginCancelEventArgs) 時，務必呼叫基底類別的方法 OnVerifyingAnswer(LoginCancelEventArgs) ，讓註冊代理接收事件。
