注解

OnSendingMail 成员资格提供程序验证用户是否为网站的有效成员之后,在将恢复的密码或新密码通过电子邮件发送给用户之前,将调用 方法。 默认实现引发 SendingMail 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

OnSendingMail 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 OnSendingMail(MailMessageEventArgs) 时,一定要调用基类的 OnSendingMail(MailMessageEventArgs) 方法,以便已注册的委托对事件进行接收。
