C#製作Windows service服務系列三–製作可控制介面的windows服務(windows service)

在前面兩篇文章中，我們可以做到自啟動windows和定時自動執行windows service

　　系列一： 製作一個可安裝、可啟動、可停止、可卸載的Windows service(downmoon原創)

　　系列二：示範一個定期執行的windows服務及調試（windows service）(downmoon)

　　系列三： windows service系列三--製作可控制介面的windows service

　　本文將重點介紹下如何通過介面控制肉眼看不到的windows service。其實主要用到的類是：

　　ServiceController ，可以看官方 的說明，如果急於看到結果，請直接往下看。

　　準備工作：假定我們已經做好一個wondows service，並且已經部署，服務名為pingServiceDemo，
　　
　　下面我們製作一個可控制的介面來操作這個windows service

　　開始：

　　第一步：建立一個winform項目，名為 CtrlPingService,添加System.ServiceProcess.dll的引用。

　　

第二步：定義變數,添加按鈕事件,主要代碼如下：

　　　　　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 = "當前服務狀態是：" + getStateForService(serverName);
        }
private void btnServiceState_Click(object sender, EventArgs e)
        {
            lbInfo.Text = "當前服務狀態是：" + 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，代碼如下： 　　

　　#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;//再次擷取服務狀態
            if (st == ServiceControllerStatus.Running)
            {
                lbInfo.Text = "服務  " + sc.ServiceName + "  已經啟動！";
            }
        }
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;//再次擷取服務狀態
            if (st == ServiceControllerStatus.Stopped)
            {
                lbInfo.Text = "服務　" + sc.ServiceName + "  已經停止！";
            }
        }
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;//再次擷取服務狀態
            if (st == ServiceControllerStatus.Paused)
            {
                lbInfo.Text = "服務　" + sc.ServiceName + "  已經暫停！";
            }
        }
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;//再次擷取服務狀態
            if (st == ServiceControllerStatus.Running)
            {
                lbInfo.Text = "服務　" + sc.ServiceName + "  已經繼續！";
            }
        }
private string getStateForService(string servername)
        {
            ServiceController sc = new ServiceController(servername);
            ServiceControllerStatus st = sc.Status;
return sc.Status.ToString();
        }
#endregion

　　ＯＫ！　最後欣賞下我們的成果：

　　

　　

　　
     邀月總結：其實WCF完全可以做到這些。這裡只是作了一個簡單示範。稍後可能會寫WCF系列學習心得。呵呵
