1. 操作WINDOW服务需要在C#里引入一个类库：System.ServiceProcess

        //监测服务是否启动
private bool ServicesExists(string serviceName)
        {
            bool isbn = false;
            //获取所有服务
            ServiceController[] services = ServiceController.GetServices();
            try
            {
                foreach (ServiceController service in services)
                {
                    if (service.ServiceName.ToUpper() == serviceName.ToUpper())
                    {
                        isbn = true;
                        break;
                    }
                }
                return isbn;
            }
            catch (Exception ex)
            {
                return false;
            }
        }

        //启动服务
