Raises the Closed event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The method is obsolete in the .NET Framework version 2.0; use the OnFormClosed method instead.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnFormClosed method also allows derived classes to handle the event without attaching a delegate. Overriding this method is the preferred technique for handling the event in a derived class.
The and OnClosing methods are not called when the Application.Exit method is called to exit your application. If you have validation code in either of these methods that must be executed, you should call the Form.Close method for each open form individually before calling the Exit method.
When overriding in a derived class, be sure to call the base class's method so that registered delegates receive the event.
The following code example demonstrates how to override the method in a class derived from Form .
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
