如何在一个 C# 中创建一个服务？

启动服务... 根据微软的说法，要启动服务，必须使用特殊工具或其特殊实用程序手动完成（使用 InstallHelper 等时）。我使用 WMI 安装。

PS 要安装启动服务，程序必须从管理员（包括管理单元）下启动。

服务的“模板”变成了这样

using System;
using System.ServiceProcess;
using System.Collections;
using System.Collections.Specialized;
using System.Windows.Forms;
using System.Threading;
using System.Management;





public partial class Service:ServiceBase  {

 static string  myname = "CMyService";

 public Service()
        {
            this.ServiceName = myname;
            this.CanStop = true;
            this.CanPauseAndContinue = false;
        }


  static public bool Run() {
        ServiceBase[] ServicesToRun = new ServiceBase[] { new Service() };
        ServiceBase.Run(ServicesToRun);
        return true;
     }


  static private volatile bool _Working;
  static private volatile bool _Worked;

  static public bool Working {  get {  return _Working; }} 



  static void MyThread(){
        while (_Working){
             Worker.current.Work();
            }
        _Worked = true;
        }



  protected override void OnStart(string[] args)
        {
         _Working = true;
         _Worked = false;
         (new Thread(new ThreadStart(MyThread))).Start();
        }

        protected override void OnStop()
        {
          _Working = false;
          while (!_Worked) Thread.Sleep(1000);    
        }

  //-----------------------------------------------------------
  // Service config for UI
  static ServiceController GetService() {
     foreach (ServiceController item in  ServiceController.GetServices())
            if (item.ServiceName == myname) return item;
     return null;
     }



  public static bool Installed {
        get { return (GetService()!=null);}

        set {
           int q = 0;
           string  servicePath = System.Reflection.Assembly.GetEntryAssembly().Location;

           //ManagementObject serv =  new ManagementObject(new ManagementScope(@"root\CIMV2"),new ManagementPath( "Win32_Service"),null);
           ManagementScope sc = new ManagementScope("root\\CIMV2");
           sc.Connect();


           if (value) { /*install*/

              ManagementObject serv = new ManagementClass(sc, new ManagementPath("Win32_Service"),null);
              q =Convert.ToInt32( serv.InvokeMethod("Create",new object[] 
               { myname, myname,  servicePath /*+" /SERVICE" /**/,  16/*own*/, 0, "Manual", 0 , ".\\LocalSystem", "", null }));                            
             }  else { /*uninstall*/
               foreach(ManagementObject item in (new ManagementObjectSearcher(sc,new ObjectQuery("select * from Win32_Service"))).Get()){

                    q =Convert.ToInt32( item.InvokeMethod("Delete",null));                    
                 }

             }
            string[]  errors = {null, "The request is not supported" ,"Access denied","The service cannot be stopped because other services that are running are dependent on it",
                 "The requested control code is not valid, or it is unacceptable to the service","The requested control code cannot be sent to the service because the state of the service 0,1,2",
                  "The service has not been started","The service did not respond to the start request in a timely fashion",
                  "Unknown failure when starting the service","path was not found",
                   "The service is already running","The database to add a new service is locked.",
                   "A dependency this service relies on has been removed from the system",
                   "The service failed to find the service needed from a dependent service",
                    "The service has been disabled from the system","The service does not have the correct authentication to run on the system.",
                 "This service is being removed from the system.","The service has no execution thread.","The service has circular dependencies when it starts.",
                  "A service is running under the same name.","The service name has invalid characters.","Invalid parameters have been passed to the service.",
                "The account under which this service runs is either invalid or lacks the permissions to run the service.",

            if (q != 0) MessageBox.Show(q > 24? q.ToString():errors[q]);
            }
      }




  public static void DoStart () {
      if (Installed) GetService().Start();
      }


  public static void DoStop () {
      if (Installed) GetService().Stop();
      }

  }

程序的文本是

    static void Main(string[] args)
    {
     int q = 0;
    try {
      q = System.Diagnostics.Process.GetCurrentProcess().SessionId;
     } catch {};
     if ((q == 0)?Service.Run() : false) return;
     if (args.Length > 0) {            
          if (args[0].ToUpper()  == "/INSTALL") { Service.Installed = true;return;}
          if (args[0].ToUpper()  == "/UNINSTALL"){Service.Installed = false;return;}
          }
     Application.EnableVisualStyles();
     Application.SetCompatibleTextRenderingDefault(false);
     Application.Run(new MainForm(args));
    }
