There are SEVERAL options. First, you can use your own COMMUNICATION mechanism to tell the ThreadStart method to finish. Alternatively the Thread class has in-built support for instructing the thread to stop. The two principle methods are Thread.Interrupt() and Thread.Abort(). The former will cause a Thread Interrupted Exception to be thrown on the thread when it next goes into a WaitJoinSleep state. In other WORDS, Thread.Interrupt is a polite way of asking the thread to stop when it is no longer doing any useful work. In contrast, Thread.Abort() throws a ThreadAbortException regardless of what the thread is doing. Furthermore, the ThreadAbortException cannot NORMALLY be caught (THOUGH the ThreadStart's finally method will be executed). Thread.Abort() is a heavy-handed mechanism which should not normally be required.
