如何暂停/暂停一个线程然后继续它？

ManualResetEvent mrse = new ManualResetEvent(false);

public void run() 
{ 
    while(true) 
    { 
        mrse.WaitOne();
        printMessageOnGui("Hey"); 
        Thread.Sleep(2000); . . 
    } 
}

public void Resume()
{
    mrse.Set();
}

public void Pause()
{
    mrse.Reset();
}

ManualResetEvent mre = new ManualResetEvent();
mre.WaitOne();  // This will wait

mre.Set(); // Tells the other thread to go again

class Program
{
    private static ManualResetEvent mre = new ManualResetEvent(false);

    static void Main(string[] args)
    {
        Thread t = new Thread(new ThreadStart(SleepAndSet));
        t.Start();

        Console.WriteLine("Waiting");
        mre.WaitOne();
        Console.WriteLine("Resuming");
    }

    public static void SleepAndSet()
    {
        Thread.Sleep(2000);
        mre.Set();
    }
}
