注解

在 OnVerifyingAnswer 将用户对密码恢复确认问题的回答发送到成员资格提供程序进行验证之前，将调用 方法。 默认实现引发 VerifyingAnswer 事件。

引发事件时，将通过委托调用事件处理程序。 有关详细信息，请参阅 处理和引发事件。

OnVerifyingAnswer 方法还允许派生类对事件进行处理而不必附加委托。 这是在派生类中处理事件的首选技术。

继承者说明

在派生类中重写 OnVerifyingAnswer(LoginCancelEventArgs) 时，一定要调用基类的 OnVerifyingAnswer(LoginCancelEventArgs) 方法，以便已注册的委托对事件进行接收。
