{

//Release the waiting thread.

Monitor.Pulse(m_smplQueue);

//Wait in the loop, while the queue is busy.

//Exit on the time-out when the first thread stops.

while(Monitor.Wait(m_smplQueue,1000))

{

//Pop the first element.

int counter = (int)m_smplQueue.Dequeue();

//Print the first element.

Console.WriteLine(counter.ToString());

//Release the waiting thread.

Monitor.Pulse(m_smplQueue);

}

}

}

//Return the number of queue elements.

public int GetQueueCount()

{

return m_smplQueue.Count;

}

static void Main(string[] args)

{

//Create the MonitorSample object.

MonitorSample test = new MonitorSample();

//Create the first thread.

Thread tFirst = new Thread(new ThreadStart(test.FirstThread));
