注解

通过FormClosed用户界面 (UI) 或通过调用方法Close (如Form类中的或ExitApplication类中) 来关闭窗体后, 会发生该事件。The FormClosed event occurs after a form is closed, either by the user, through the user interface (UI), or programmatically, through calls to methods such as Close in the Form class, or Exit in the Application class.

创建 FormClosedEventHandler 委托时,需要标识将处理该事件的方法。When you create a FormClosedEventHandler delegate, you identify the method that will handle the event. 若要将事件与事件处理程序关联,请将该委托的一个实例添加到事件中。To associate the event with your event handler, add an instance of the delegate to the event. 除非移除了该委托,否则每当发生该事件时就会调用事件处理程序。The event handler is called whenever the event occurs, unless you remove the delegate. 有关事件处理程序委托的详细信息, 请参阅处理和引发事件For more information about event-handler delegates, see Handling and Raising Events.
