C#制作Windows service服务系列三制作可控制界面的Windows服务(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;
 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
