暂停线程执行

private readonly ManualResetEvent _resumeEvent = new ManualResetEvent(false);        
private volatile bool _blnPaused; //记录运行状态是否暂停

        /// <summary>
        /// 暂停
        /// </summary>
        public void Pause()
        {
            _resumeEvent.Reset();
            _blnPaused = true;
        }

        /// <summary>
        /// 重启
        /// </summary>
        public void Resume()
        {
            _blnPaused = false;
            _resumeEvent.Set();
        }

...

线程方法中添加下面的代码

          if (_blnPaused) //如果暂停则等待
          {
             _resumeEvent.WaitOne();
          }
          else
          {
          ｝
