[开发笔记]-控制Windows Service服务运行

用代码实现动态控制Service服务运行状态。

效果图：

代码：

        #region 启动服务
        /// <summary>
        /// 启动服务
        /// </summary>
        /// <param name="scname"></param>
        void XServiceStart(string scname)
        {
            ServiceController sc = new ServiceController(scname);
            ServiceControllerStatus st = sc.Status;
            switch (st)
            {
                case ServiceControllerStatus.StopPending:
                case ServiceControllerStatus.Stopped:
                    sc.Start();//启动服务
                    //等待服务达到指定状态
                    sc.WaitForStatus(ServiceControllerStatus.Running);
                    break;
                default:
                    break;
            }

        }

对于Service服务的“开启”，“停止”操作，创建的Service服务程序默认是支持的。而“暂停”，“恢复”操作，需要在服务的属性中进行开启设置才可以。

CanPauseAndContinue          服务是否接受暂停或继续运行的请求

在win7及以上系统上操作时，需要以管理员身份运行才能操作Service服务，否则程序会异常。如何让程序获得管理员权限，可以查看我前一篇文章：
