我需要在.CS文件中关闭一个服务,相关代码如下:                      ServiceController myService2 = new ServiceController("***");
                    if (myService != null)
                    {
                     if (myService.Status != ServiceControllerStatus.Stopped)
                      {
                          bool l = myService.CanStop;
                          try
                           { myService.Stop();}catch(Exception er){ string msg = er.Message;}
                      }
                    }运行到myService.Stop()时会出错:
Cannot open *** service on computer '.'.
