当我们创建一个WINDOWS服务后，却发觉我们所创建的服务没有相关的描述。（你可以打开服务管理器程序查看）。而System.ServiceProcess.ServiceBase这些相关的类都没有提供这方面的信息。同样如果我们需要给我们的服务加上恰当的描述，我们也只能通过非托管代码来处理。

当我们给服务增加安装包时，我们可以在ProjectInstaller里加上我们修改服务描述的代码
private void InitializeComponent()
{
//这里要增加代码
this.AfterInstall += new System.Configuration.Install.InstallEventHandler(this.ProjectInstaller_AfterInstall);
}

{
throw new Exception('不能打开服务管理器.');
}
iSCManagerLockHandle = modAPI.LockServiceDatabase(iSCManagerHandle);

}
在安装完成后，我们对服务进行。这里可以修改的内容包括服务的描述，服务的故障处理等.
如果你在安装时，需要对服务进行自动处于运行状态，或卸载时需要自动将服务也卸载，你只要注册
this.BeforeUninstall+=new InstallEventHandler(ProjectInstaller_BeforeUninstall);
this.Committed+=new InstallEventHandler(ProjectInstaller_Committed);
这二个事件
Committed事件，在这里可以将安装的服务进行调整到运行状态
BeforeUninstall事件，您可以在这里将服务自动卸载掉
