.net – 一些旧代码的线程问题

从以下代码抛出错误：

private void Submit(WorkItem work)
    {
        this.AdjustPoolSize();

        lock (this.workQueue.SyncRoot)
        {
        //Monitor.Enter(workQueue);
        this.workQueue.Enqueue(work);
            Monitor.Pulse(this.workQueue.SyncRoot);
        //Monitor.Exit(workQueue);
        }
    }

评论的代码是我如何交付代码.不幸的是,我根本不了解这个项目,只是来解决这个问题.我们看到的错误是：

System.Threading.SynchronizationLockException was unhandled by user code
  Message=Object synchronization method was called from an unsynchronized block of code.
  Source=mscorlib
  StackTrace:

  InnerException:

从它的外观来看,当事实并非如此时,某些东西被触发为“可用”.我试图谷歌这个,发现http://bbellomo.blogspot.com/2007/03/object-synchronization-method-was.html,但这对我没那么帮助,因为我不太了解他的问题和解决方案.

希望有人可以给我一些提示.

谢谢！
