多线程与睡眠

Question

这是三个线程的正常使用吗？ 我可以使用一个线程作为GUI表单，一个用于计算，最后一个作为主人来杀死其他人吗？

这里我开始我的三个线程，当我按下ESC键时它会终止所有进程。这是一种正常的做法，还是更精心的做法？

namespace ThreadingTest
{
class Program
{
    static void Main(string[] args)
    {
        bool exit = false;
        System.Threading.Thread myThread;
        System.Threading.Thread mysecondthread;
        System.Threading.Thread Killingthread;

        myThread = new System.Threading.Thread(new System.Threading.ThreadStart(ThreadLoop));
        mysecondthread = new System.Threading.Thread(new System.Threading.ThreadStart(SecondThreadwork));
        Killingthread = new System.Threading.Thread(new System.Threading.ThreadStart(KillProcess));

        myThread.Start();
        mysecondthread.Start();
        Killingthread.Start();
        while (exit == false)
        {
            var FirstThreadState = myThread.ThreadState;
            var SecondThreadState = mysecondthread.ThreadState;
            var ThirdThreadState = Killingthread.ThreadState;
            Console.WriteLine(ThirdThreadState.ToString());
            if (ThirdThreadState == System.Threading.ThreadState.Stopped) exit = true;
            System.Threading.Thread.Sleep(500);
        }
        myThread.Abort();
        Console.WriteLine("first thread ended.");
        mysecondthread.Abort();
        Console.WriteLine("second thread ended.");
        Killingthread.Abort();
        Console.WriteLine("third thread ended.");
    }
    public static void ThreadLoop()
    {
        while (System.Threading.Thread.CurrentThread.IsAlive)
        {
           System.Threading.Thread.Sleep(500);

            Console.WriteLine("I'm working...");
        }
    }
    public static void SecondThreadwork()
    {
        while (System.Threading.Thread.CurrentThread.IsAlive)
        {
            System.Threading.Thread.Sleep(500);
            Console.WriteLine("me too...");
        }
    }
    public static void KillProcess()
    {
    do {
        while (!Console.KeyAvailable)
        {
            System.Threading.Thread.Sleep(500);
            Console.WriteLine("third ON."); // Do something
        }      
        } while (Console.ReadKey(true).Key != ConsoleKey.Escape);

    }
}
}

谢谢
