Form.OnFormClosed(FormClosedEventArgs) Form.OnFormClosed(FormClosedEventArgs) Form.OnFormClosed(FormClosedEventArgs) Form.OnFormClosed(FormClosedEventArgs) Method

定义

引发 FormClosed 事件。Raises the FormClosed event.

protected:
 virtual void OnFormClosed(System::Windows::Forms::FormClosedEventArgs ^ e);
protected virtual void OnFormClosed (System.Windows.Forms.FormClosedEventArgs e);
abstract member OnFormClosed : System.Windows.Forms.FormClosedEventArgs -> unit
override this.OnFormClosed : System.Windows.Forms.FormClosedEventArgs -> unit
Protected Overridable Sub OnFormClosed (e As FormClosedEventArgs)

参数

注解

@No__t-0 方法将从关联的 @no__t 的 @no__t 的集合中删除当前窗体。The OnFormClosing method removes the current form from the OpenForms collection of the associated Application.

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.

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

继承者说明

在派生类中重写 OnFormClosed(FormClosedEventArgs) 时,一定要调用基类的 OnFormClosed(FormClosedEventArgs) 方法,以便已注册的委托对事件进行接收。When overriding OnFormClosed(FormClosedEventArgs) in a derived class, be sure to call the base class's OnFormClosed(FormClosedEventArgs) method so that registered delegates receive the event.
