How to dispose thread in c#

Question

I have used threading in my web application which I have mentioned below:

var t1 = new Thread(F1);
            t1.IsBackground = true;
            t1.Start();

            var t2 = new Thread(F2);
            t2.IsBackground = true;
            t2.Start();

            var t3 = new Thread(F3);
            t3.IsBackground = true;
            t3.Start();

            var t4 = new Thread(F4);
            t4.IsBackground = true;
            t4.Start();


            t1.Join();
            t2.Join();
            t3.Join();
            t4.Join();

This is working fine and giving me the desired output.

Do I need to kill/Dispose the thread after this, if yes then how ? Please guide.

I have told that if I do not dispose it, it might raise performance issue.

Answer 1

The call to Join() is what de-allocates the thread. You don't have to do anything else. Just make sure that the threads clean up any resources they might be using before they exit.

That said, I would urge you to look into using the thread pool or the Task Parallel Library (TPL) rather than explicitly managing threads. They're easier to use, and handle this kind of thing much more smoothly.
