C#制作Windows service服务系列三--制作可控制界面的windows服务(windows service)

在前面两篇文章中，我们可以做到自启动windows和定时自动执行windows service

　　系列一： 制作一个可安装、可启动、可停止、可卸载的Windows service(downmoon原创)

　　系列二：演示一个定期执行的windows服务及调试（windows service）(downmoon)

　　系列三： windows service系列三--制作可控制界面的windows service

　　本文将重点介绍下如何通过界面控制肉眼看不到的windows service。其实主要用到的类是：

　　ServiceController ，可以看官方 的说明，如果急于看到结果，请直接往下看。

　　准备工作：假定我们已经做好一个wondows service，并且已经部署，服务名为pingServiceDemo，
　　
　　下面我们制作一个可控制的界面来操作这个windows service

　　开始：

　　第一步：新建一个winform项目，名为 CtrlPingService,添加System.ServiceProcess.dll的引用。

　　

第二步：定义变量,添加按钮事件,主要代码如下：

　　　　　private System.Windows.Forms.Button btnStart;
        private System.Windows.Forms.Button btnStop;
        private System.Windows.Forms.Button btnExit;
        private System.ServiceProcess.ServiceController sController;
        private Label lbInfo;
        private Button ftnPause;
        private Button btnResume;
        private Label lbServiceName;
        private TextBox txtServerName;
        private Button btnServiceState;
        private string serverName;
 
　　#region Ecents

        private void frmMain_Load(object sender, EventArgs e)
        {
            if (serverName == null) { serverName = txtServerName.Text.Trim(); }
            lbInfo.Text = "当前服务状态是：" + getStateForService(serverName);
        }
        private void btnServiceState_Click(object sender, EventArgs e)
        {
            lbInfo.Text = "当前服务状态是：" + getStateForService(serverName);
        }
        private void btnStart_Click(object sender, System.EventArgs e)
        {
            runService(serverName);
        }
        private void btnStop_Click(object sender, System.EventArgs e)
        {
            killService(serverName);
        }
        private void ftnPause_Click(object sender, EventArgs e)
        {
            pauseService(serverName);
        }
        private void btnResume_Click(object sender, EventArgs e)
        {
            resumeService(serverName);
        }
        private void btnExit_Click(object sender, System.EventArgs e)
        {
            this.Close();
            Application.Exit();
        }
 #endregion

第三步：添加用到的方法，代码如下： 　　

　　#region Methods

        private void runService(string servername)
        {
            ServiceController sc = new ServiceController(servername);
            ServiceControllerStatus st = sc.Status;
            switch (st)
            {
                case ServiceControllerStatus.StopPending:
                case ServiceControllerStatus.Stopped:
                    sc.Start();
                    break;
                default: break;
            }
            sc.WaitForStatus(ServiceControllerStatus.Running);
            st = sc.Status;//再次获取服务状态
            if (st == ServiceControllerStatus.Running)
            {
                lbInfo.Text = "服务  " + sc.ServiceName + "  已经启动！";
            }
        }
        private void killService(string servername)
        {
            ServiceController sc = new ServiceController(servername);
            ServiceControllerStatus st = sc.Status;
            switch (st)
            {
                case ServiceControllerStatus.Running:
                case ServiceControllerStatus.StartPending:
                case ServiceControllerStatus.Paused:
                case ServiceControllerStatus.PausePending:
                case ServiceControllerStatus.ContinuePending:
                    sc.Stop();
                    sc.WaitForStatus(ServiceControllerStatus.Stopped);
                    break;
            }
            st = sc.Status;//再次获取服务状态
            if (st == ServiceControllerStatus.Stopped)
            {
                lbInfo.Text = "服务　" + sc.ServiceName + "  已经停止！";
            }
        }
        private void pauseService(string servername)
        {
            ServiceController sc = new ServiceController(servername);
            ServiceControllerStatus st = sc.Status;
            switch (st)
            {
                case ServiceControllerStatus.Running:
                case ServiceControllerStatus.StartPending:
                    sc.Pause();
                    sc.WaitForStatus(ServiceControllerStatus.Paused);
                    break;
            }
            st = sc.Status;//再次获取服务状态
            if (st == ServiceControllerStatus.Paused)
            {
                lbInfo.Text = "服务　" + sc.ServiceName + "  已经暂停！";
            }
        }
        private void resumeService(string servername)
        {
            ServiceController sc = new ServiceController(servername);
            ServiceControllerStatus st = sc.Status;
            switch (st)
            {
                case ServiceControllerStatus.Paused:
                case ServiceControllerStatus.PausePending:
                    sc.Continue();
                    sc.WaitForStatus(ServiceControllerStatus.Running);
                    break;
            }
            st = sc.Status;//再次获取服务状态
            if (st == ServiceControllerStatus.Running)
            {
                lbInfo.Text = "服务　" + sc.ServiceName + "  已经继续！";
            }
        }
        private string getStateForService(string servername)
        {
            ServiceController sc = new ServiceController(servername);
            ServiceControllerStatus st = sc.Status;
            return sc.Status.ToString();
        }
  #endregion

　　ＯＫ！　最后欣赏下我们的成果：

　　

　　

　　
     邀月总结：其实WCF完全可以做到这些。这里只是作了一个简单演示。稍后可能会写WCF系列学习心得。呵呵
