I created a thread and that thread can be suspended. So, how do I kill or terminate a suspended thread?

I tried to ABORT the thread and I got a runtime error message saying that the thread is suspended and it can't be aborted. I've looked for terminate method or something similar and it doesn't seem to exist.

myThread := new Thread(@BigLoop);
myThread.Start;

myThread.Suspend;
myThread.Abort; <<<===exception is raised.

So, how do you kill or terminate a suspended thread?

After I resumed the suspended thread, I was able to abort the thread;

myThread := new Thread(@BigLoop);
myThread.Start;

myThread.Suspend;


if MyThread.ThreadState = ThreadState.Suspended then
   myThread.Resume;

myThread.Abort;

Note that it's unadvisable to use abort. A better solution would be to use a waithandle (autoresetevent/manualresetevent) to notify the thread that it should stop running. Remember that "Abort" doesn't work on anything that calls into native code, like com or pinvoke.

    Ck. That's true but what if you are trying to abort a thread on your program shutdown. Does it matter then? – ThN Dec 23 '12 at 15:05
