hello

i have written a winApp with some threads , but when i close the main form(the winApp),it cant be closed completely,there is still
some thread run background. i have aborted the threads i created
in closingwindow event.

what may be the problem? how to avoid it?

Try making them background thread.

Code:

myThread.IsBackground = true;

Do this just after you've created the thread.

Your application will keep running as long as there is at least 1 NON background thread running.

Your application will not terminate as long as there is atleast one thread still running even if it's idle/asleep/background. When you close the last loaded form/UI interface, you will simply exit the message loop. If another thread is alive it will not end.
It's good you found the thread that was still alive.
I suggest you add Environment.Exit(0) to your code. It will terminate any thread you might have forgot about.
