Interrupt a sleeping Thread

Question

Is there a way to Interupt a sleeping thread? If I have code similar to this.

while(true){
    if(DateTime.Now.Subtract(_lastExecuteTime).TotalHours > 1)         


        

Answer 1

Instead of using Thread.Sleep, you can use Monitor.Wait with a timeout - and then you can use Monitor.Pulse from a different thread to wake it up.

Don't forget you'll need to lock on the monitor before calling either Wait or Pulse:

// In the background thread
lock (monitor)
{
    // If we've already been told to quit, we don't want to sleep!
    if (somethingIndicatingQuit)
    {
        break;
    }
    Monitor.Wait(monitor, TimeSpan.FromSeconds(10));
    if (somethingIndicatingQuit)
    {
        break;
    }
}

// To wake it up...
lock (monitor)
{
    somethingIndicatingQuit = true;
    Monitor.Pulse(monitor);
}
