使用线程来控制进度条

创建一个Windows程序，在窗体中添加两个进度条PrograssBar1~ProgressBar2,使用线程来控制进度条，实现进度不一的两条进度条同时操作。

        Thread MyThread2;
        void GetProgress2()
        {
            while (progressBar1.Value < 100)
            {
                progressBar1.PerformStep();
                if (progressBar2.Value >= 100)
                {
                    if (MyThread1.IsAlive)
                    {

                    }
                }
                else
                {
                    if (progressBar1.Value >= 100) 
                    {
                        progressBar1.Value = 0;
                    }
                }
                Thread.Sleep(50);
            }
        }
        void GetProcess1()
        {
            while (progressBar2.Value < 100) 
            {
                progressBar2.PerformStep();
                if (progressBar2.Value >= 100)
                {
                    MessageBox.Show("进度完成");
                     if (MyThread2.IsAlive)
                    {
                        MyThread2.Abort();
                    }
                }
                Thread.Sleep(50);
            }
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            progressBar1.Step = 10;
            progressBar2.Step = 1;
            CheckForIllegalCrossThreadCalls = false;
            MyThread1 = new Thread(new ThreadStart(GetProcess1));
            MyThread2 = new Thread(new ThreadStart(GetProgress2));
            MyThread1.Priority = ThreadPriority.Lowest;
            MyThread1.Start();
            MyThread2.Start();
        }
    }
}
