How to exit all running threads?

The following code does not exit the application. How can I exit the application and make sure all the running threads are closed?

foreach (Form form in Appl         


        

Answer 1

I went through a similar issue in my software, but unfortunately just making the threads to work in background didn't solve the issue. In fact while the thread brings back data (the main software is data driven) and if I close the application, it results to Windows Error, giving rise to a debugging message.

So what actually worked for me:

Step 1: Made all threads run in background such as

Thread aThread = new Thread(MethodName);
aThread.IsBackground = true; //<-- Set the thread to work in background
aThread.Start();

Step 2: In the closing action of the form/application call the Environment.Exit method, such as

Environment.Exit(Environment.ExitCode);

This kept the memory managed perfectly, with no memory leak.

Hope this helps.
