Right way to close WPF GUI application: GetCurrentProcess().Kill(), Environment.Exit(0) or this.Shutdown()
Solution 1:
Application.Current.Shutdown()
is the proper way to shutdown an application. Generally because fire the exit events that you can handle more
Process.GetCurrentProcess().Kill()
should be used when you want to kill the application. more
Ad1. The nature of those methods are totally different. The shutdown process can be paused to end some operations, kill force the application to close.
Ad2. Probably Kill()
will be the fastest way, but this is something like kernel panic.
Ad3. Shutdown because it fires the close event
Ad4. That depend what this
is.
Solution 2:
Use Application.Current.Shutdown();
Add ShutdownMode="OnMainWindowClose" in App.xaml
Solution 3:
private void ExitMenu_Click(object sender, RoutedEventArgs e)
{
Application.Current.Shutdown();
}
Solution 4:
@Damian Leszczyński - Vash's answer pretty much covers the 4 specific questions you asked. For your final question on Application.Exit()
, that's an event you can subscribe to, not a method that you can call. It should be used like this:
Application.Current.Exit += CurrentOnExit;
//this.Exit += CurrentOnExit; would also work if you're in your main application class
...
private void CurrentOnExit(object sender, ExitEventArgs exitEventArgs)
{
//do some final stuff here before the app shuts down
}
