threads

in my asp.net web application, I have a process that is run on the thread and my requirement is to add a Stop Process button which will stop the all running thread which is created inside that method only and I also want to end the process gracefully means the thread is calling many methods and when the thread is aborted the current method must be completed.

Thread threadrunAutoFilters = new Thread(AFController.RunSelectedFilters);
            Thread.CurrentThread.Name = CurrentUser.UserName.Trim();
            threadrunAutoFilters.Start();

my Stop Process button will call another web method in this method I want to write logic to get all running thread which is created by above code and terminate the running thread.

what is the best way to do this.

What I have tried:

I have added a static Hashtable object and store thread object in it and on my Stop Process method I am iterating hashTable to get the thread object which is running and abort() it.
