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.

OnResize方法还可使派生的类处理事件,而不必附加委托。The OnResize method also enables 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

在派生类中重写 OnResize(EventArgs) 时,一定要调用基类的 OnResize(EventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnResize(EventArgs) in a derived class, be sure to call the base class's OnResize(EventArgs) method so that registered delegates receive the event. OnResize(EventArgs)方法可以调用在构造期间,因此,如果您重写OnResize(EventArgs)控件构造函数调用之前,可以调用它。The OnResize(EventArgs) method can be called during construction, so if you override OnResize(EventArgs) it can be called before the control constructor is called.
