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:
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。
