Canceling Multiple Threads

Question

I am trying to cancel multiple threads at the click of a button in WinForms. My threading method is listed below, which the thread then calls another method. I created the thread as a class variable and then loops through and creates a new one for however many threads the user wants. I want to stop call threads at the click of a stop button. I could not find any similar questions. Originally, in my generate() method below, I would check if the button was clicked and would Abort(), but this only works if the button is clicked then and there.

private static Thread t;

  private void threader()
        {


            int wait = (int)(waiter.Value * 60000);
            for(int i = 0; i < numOfThread.Value; i++)
            {
                try
                {
                    t = new Thread(new ThreadStart(generateBlizz));
                    t.IsBackground = true;
                    
                    t.Start();
                }catch(ThreadAbortException e)
                {

                }

            }
