In the days of v1.1, the need to start a new thread with parameters almost arises on every instance - there was no way, at least none that I know of. However, v2.0 of the .Net Framework allows you to start a new thread and also pass a parameter to it. It doesn't get any better. I have been messing around with some threading recently and it came in handy. Sample code:

        private void BeginThreading()
        {
            int id = 1;

            // Method #1
            new System.Threading.Thread(
                new System.Threading.ParameterizedThreadStart(DoStuff)).Start(id);

            // Method #2
            System.Threading.Thread 
                newDoStuff = new System.Threading.Thread(
                new System.Threading.ParameterizedThreadStart(DoStuff));

            newDoStuff.Start(id);
        }

        private void DoStuff(object id)
        {
            int newId = (int) id;
            // do stuff here
        }
