注解

引发事件时,将通过委托调用事件处理程序。Raising an event invokes the event handler through a delegate. 有关详细信息,请参阅处理和引发事件For more information, see Handling and Raising Events.

OnMetaDataChanged 方法还允许派生类对事件进行处理而不必附加委托。The OnMetaDataChanged method also allows derived classes to handle the event without attaching a delegate. 这是在派生类中处理事件的首选技术。This is the preferred technique for handling the event in a derived class.

继承者说明

重写时OnMetaDataChanged(EventArgs)在派生类中,请务必调用基类的OnMetaDataChanged(EventArgs)方法,以便已注册的委托接收事件。When overriding OnMetaDataChanged(EventArgs) in a derived class, be sure to call the base class' OnMetaDataChanged(EventArgs) method so that registered delegates receive the event.
