Does Application.Exit() kill background threads?

Question

I created a form which runs multiple background threads. I added another class which handles exceptions and errors if any. When the code runs, if an error occurs that should force the application to close can I just use Application.Exit()? Will that kill the background threads as well?

Answer 1

No, it will not. Application.Exit() will simply force the windows message pump to post a Quit message, which will terminate your application's main thread. However, the process itself will continue to run until the background threads complete.

Update: as commenters have correctly pointed out, if your thread's IsBackground property is set to True, terminating the main thread via Application.Exit() will shut down the process.
