Pausing a thread until manually resumed [duplicate]

Question

How do I put a thread into paused/sleep state until I manually resume it in c# ?

Currently I am aborting the thread but this is not what I am looking for. The thread should sleep/pause until it something triggers it to wake up.

You should do this via a ManualResetEvent.

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

On another thread, obviously you'll need a reference to the ManualResetEvent instance.

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

A full example which will print some text, wait for another thread to do something and then resume:

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();
    }
}

Look into AutoResetEvent or ManualResetEvent.
