Destroy all thread before open another wpf windows

Question

I am using multiple thread in wpf windows.

I am using this.Close() to close the window, and open another window using newWindow.Show().

Code:

// open new windows newWindow newWindow = new newWindow(); this.Close(); newWindow.Show(); // close window private void OnClosed(object sender, EventArgs e) { // stop some events d.StopEvents(); }

It will takes long time to reach StopEvents.

If I use Environment.Exit(0); it will close the application, I don't want that.

Thanks.

Have you considered keeping track of your threads in a List<Thread> and calling Abort on them? — Roland Mai

You really don't want to be using Abort unless you have no other choice as without very careful usage you may as well consider the method to be called, PleaseCorruptMyApplicationStateRandomly — Chris Chilvers

What are your threads doing? A common pattern is for working threads to periodically check a flag to see whether they need to close themselves. It's much safer for each thread to do that than for another tread to abort it.

You might also want to consider using the Parallel extensions (TPL) as this makes threading much easier, and comes with concepts like Cancellation baked in.
