c# Threading: How to manage stacking calls

[Ramk]

Hmm...little confused on what do you want to achieve.
I can give a other way to handle more number of threads. Use ThreadPool instead.

I have a timer T that launches an event on each tick:

        void t_Tick(object sender, EventArgs e)
        {
            System.Threading.Thread TickThread = new System.Threading.Thread(OnTick);
            TickThread.Start();
        }

        private void OnTick()
        {
            lock (this)
            {
                System.Threading.Thread.Sleep(10000);//in reality some long process
            }
        }

Now, imagine the sleep is longer than the tick-time. I am assuming that the threads will start stacking up waiting for the lock to clear. How do I go about discarding/ignoring calls until the lock is cleared.

cheers,
