c# - How do I exit a WPF application programmatically?

In the few years I've been using C# (Windows Forms), I've never used WPF. But, now I love WPF, but I don't know how I am supposed to exit my application when the user clicks on the Exit menu item from the File menu.

I have tried:

this.Dispose();
this.Exit();
Application.ShutDown();
Application.Exit();
Application.Dispose();

Among many others. Nothing works.

Answer

To exit your application you can call

System.Windows.Application.Current.Shutdown();

As described in the documentation to the Application.Shutdown method you can also modify the shutdown behavior of your application by specifying a ShutdownMode:

Shutdown is implicitly called by Windows Presentation Foundation (WPF) in the following situations:

• When ShutdownMode is set to OnLastWindowClose.


• When the ShutdownMode is set to OnMainWindowClose.


• When a user ends a session and the SessionEnding event is either unhandled, or handled without cancellation.

Please also note that Application.Current.Shutdown(); may only be called from the thread that created the Application object, i.e. normally the main thread.
