当我们需要一个程序长期运行,但是不需要界面显示时可以考虑使用Windows Service来实现。这篇博客将简单介绍一下如何创建一个Windows Service,安装/卸载Windows Service。

新建Windows Service项目:

C# 创建Windows Service-LMLPHP

删除自动生成的Service1.cs文件,新建WindowsService类,继承ServiceBase。

    class WindowsService : ServiceBase
{
public WindowsService()
{
this.ServiceName = "Test Windows Service";
this.EventLog.Log = "Application"; this.CanHandlePowerEvent = true;
this.CanHandleSessionChangeEvent = true;
this.CanPauseAndContinue = true;
this.CanShutdown = true;
this.CanStop = true;
} #region
// 可以把需求实现代码放置在重写方法内
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
} protected override void OnStart(string[] args)
{
base.OnStart(args);
} protected override void OnStop()
{
base.OnStop();
} protected override void OnPause()
{
base.OnPause();
} protected override void OnContinue()
{
base.OnContinue();
} protected override void OnShutdown()
{
base.OnShutdown();
} protected override void OnCustomCommand(int command)
{
base.OnCustomCommand(command);
} protected override bool OnPowerEvent(PowerBroadcastStatus powerStatus)
{
return base.OnPowerEvent(powerStatus);
} protected override void OnSessionChange(SessionChangeDescription changeDescription)
{
base.OnSessionChange(changeDescription);
}
#endregion
}

新建WindowsServiceInstaller类,添加System.Configuration.Install引用,

    [RunInstaller(true)]
class WindowsServiceInstaller : Installer
{
public WindowsServiceInstaller()
{
ServiceProcessInstaller serviceProcessInstaller = new ServiceProcessInstaller();
ServiceInstaller serviceInstaller = new ServiceInstaller(); serviceProcessInstaller.Account = ServiceAccount.LocalSystem;
serviceProcessInstaller.Username = null;
serviceProcessInstaller.Password = null; serviceInstaller.DisplayName = "CSharp Windows Service";
serviceInstaller.StartType = ServiceStartMode.Automatic; serviceInstaller.ServiceName = "Windows Service"; this.Installers.Add(serviceProcessInstaller);
this.Installers.Add(serviceInstaller);
}
}

编译项目,此时编译完的CSWindowsService.exe运行后提示:

C# 创建Windows Service-LMLPHP

我们需要通过installutil.exe来部署Windows Service。

以管理员身份运行Developer Command Prompt。部署命令:installutil /i 文件路径

例如:installutil /i D:\CSWindowsService.exe

卸载命令 installutil /u 文件路径。

到这里,一个简单的Windows Serive就讲完了。
