When we call Abort() method in Threading,and For conditions? Is there any validations to check before Abort the thread?

Question

I'm getting ThreadAbortException when call Abort() method, and I referred to solve this in Stack Overflow that they said to use Thread.ResetAbort() method before ending the thread, but It's not clear to me.

Please suggest me where can I use ResetAbort method. I'm getting that exception in marked line when call the Abort() method.

while (true)
{
    Group g = null;
    if (countGroupsList != null)
    {
        lock (countGroupsList.SyncRoot) // Exception here
        {
            if (groupsCounter < countGroupsList.Count)
            {
                g = (Group)countGroupsList[groupsCounter];
                groupsCounter++;
            }
         }
    }

Thread.Abort is a rude way to kill a thread. But if you really want to do so you can just ignore the exception. It's the way the thread says: Ouch, I'm dying.

You also can catch this exception and use the Thread.Abort method in your catch block. But that will prevent the thread to be killed.
