如何在新线程中运行ProgressBar Form并使用C＃对其进行管理？

Question

I have simple form with progress bar:

Like this: http://i.stack.imgur.com/jrM7Z.png

I want start progress bar form before start hard method.

For progress bar i need new thread.

My code is:

        Thread myThread = new System.Threading.Thread(delegate () {
            new ProgressBarForm().Visible = true;
        });
        myThread.Start();
        hardMethodForAlongTime();

But if I run the code my progress bar lag and not working.

How can I do this? And, can i stop thread using myThread.Stop() after hardMethodForAlongTime() ? Or is there any better solution?

        Thread myThread = new System.Threading.Thread(delegate () {
            new ProgressBarForm().Visible = true;
        });
        myThread.Start();
        hardMethodForAlongTime();
        myThread.Stop(); //stop?

Thank you for your replye.
