Form.OnFormClosed(FormClosedEventArgs) 方法

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

e
FormClosedEventArgs

包含事件数据的 FormClosedEventArgsA FormClosedEventArgs that contains the event data.

注解

OnFormClosing 方法从关联 ApplicationOpenForms 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.
