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

原文:http://blog.csdn.net/downmoon/article/details/4771990

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(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：

[c-sharp] view plain copy print ?

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

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：

[c-sharp] view plain copy print ?

switch (st)

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)
{

}
}
private void resumeService(string servername)
{

ServiceControllerStatus st = sc.Status;
switch (st)
{
case ServiceControllerStatus.Paused:

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();

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
