                    System.Threading.Timer t = null;
                  using(  t = new System.Threading.Timer((o) => { _DoWork(); }, null, 0, 0);
                            Thread.sleep(10);//需要一定时间以让timer触发
                            防止被直接回收
                   }
                   
                    
                    

                }
            }
        }

        public void DoWork()
        {
            Enable = true;
            _DoWork();
        }
    }
}

当需要一个任务持续进行时，可以在任务退出时启动一个新的线程（使用ThreadPool），或者启动以个新的定时器
