如何在C#中创建可以使用GUI*或*作为Windows服务运行的Windows应用程序？

   public partial class MyService : ServiceBase

   {

       public static void Main()

       {

           if (Environment.UserInteractive)

           {

               // 如果在交互模式下运行（即GUI模式），则启动GUI

               Application.EnableVisualStyles();

               Application.SetCompatibleTextRenderingDefault(false);

               Application.Run(new MyServiceGUI());

           }

           else

           {

               // 如果在服务模式下运行，则启动服务

               ServiceBase[] ServicesToRun;

               ServicesToRun = new ServiceBase[]

               {

                   new MyService()

               };

               ServiceBase.Run(ServicesToRun);

           }

       }

       // 其他服务代码

   }

   public partial class MyServiceGUI : Form

   {

       private ServiceController serviceController;

       public MyServiceGUI()

       {

           InitializeComponent();

           serviceController = new ServiceController("MyService");

       }

       private void startButton_Click(object sender, EventArgs e)

       {

           serviceController.Start();

       }

       private void stopButton_Click(object sender, EventArgs e)

       {

           serviceController.Stop();

       }

       // 其他GUI代码

   }
