Producer and multi-consumer sample code using C# (2)

If we use concurrent queue, we can just throw away all the complicated lock mechanism or concurrency and focus on the logic itself. Not sure if c# concurrent queue implemented it with lock free mechanism but producer-consumer code can be written in less than 100 lines.

namespace SimpleProducerConsumer

    public Producer(ConcurrentQueue<int> q)
    {
      this.q = q;
    }

    public void Run()
    {
      while (true)
      {
        int w;
        Console.Write("Gimme a work: ");
        w = Convert.ToInt32(Console.ReadLine());
        this.q.Enqueue(w);
        Console.WriteLine();
      }
    }
  }

  class Consumer
  {
    private ConcurrentQueue<int> q;

    public Consumer(ConcurrentQueue<int> q)
    {
      this.q = q;
    }

    {
      while (true)
      {
        int w = -1;
        if (q.TryDequeue(out w))
        {
          Console.WriteLine("\nExtracted {0} from the queue and processed", w);
        }
