I'm writing a music player using NAudio. Before I close the player, I would like to call some methods that stop the playback. How do I do this?

    WPF? Winforms? Something else? – Oded Dec 17 '11 at 19:43

    It should automatically stop playing when the process exits. If it does keep going then you have a threading problem in your code. Look at the Thread.IsBackground property for a quick fix. Debug + Break All to debug it. AppDomain.ProcessExit is an event you're asking about. – Hans Passant Dec 17 '11 at 19:52

WinForms

Subscribe to the Application.ApplicationExit event and in the event handler do your shutdown code.

WPF

Subscribe to the Application.Exit event and in the event handler do your shutdown code.

I think that Form.closed event would be good as well.

edit: only if you have one form

  • music players have only one form I guess and when I want to close it I simply close the window. – geniaz1 Dec 17 '11 at 19:58

    Bad assumption. What about configuration forms? About form? Don't assume. – Oded Dec 17 '11 at 20:00
  • In the programs that I wrote the user cannot switch to the main form so the other form will lose focus. – geniaz1 Dec 17 '11 at 20:07
  • Is this an application that you have written? – Oded Dec 17 '11 at 20:09
  • Yes, just like that AboutDialog dlg = new AboutDialog(); dlg.ShowDialog(this); dlg.Dispose(); – geniaz1 Dec 17 '11 at 20:13
  • I mean, is the application the OP is asking about one of the applications you have written? If not, how can you assume you know how it was coded? – Oded Dec 17 '11 at 20:14
