.net - 如何让.NET Windows服务在安装后立即启动？

Question

除了 service.StartType = ServiceStartMode.Automatic 我的服务在安装后不会启动

解决方案

将此代码插入我的 ProjectInstaller

protected override void OnAfterInstall(System.Collections.IDictionary savedState)
{
    base.OnAfterInstall(savedState);
    using (var serviceController = new ServiceController(this.serviceInstaller1.ServiceName, Environment.MachineName))
        serviceController.Start();
}

感谢 ScottTx 和 Francis B。

我发布了用 C# 创建 Windows 服务的分步过程 here 。听起来您至少到目前为止，现在您想知道安装后如何启动该服务。将 StartType 属性设置为“自动”将导致服务在重新引导系统后自动启动，但它不会(正如您所发现的)在安装后自动启动服务。

我不记得最初在哪里找到它(也许是 Marc Gravell？)，但我确实在网上找到了一个解决方案，允许您通过实际运行服务本身来安装和启动服务。以下是分步操作:

1. 按如下方式构建服务的 Main() 函数:

   static void Main(string[] args)
   {
       if (args.Length == 0) {
           // Run your service normally.
           ServiceBase[] ServicesToRun = new ServiceBase[] {new YourService()};
           ServiceBase.Run(ServicesToRun);
       } else if (args.Length == 1) {
           switch (args[0]) {
               case "-install":
                   InstallService();
                   StartService();
                   break;
               case "-uninstall":
                   StopService();
                   UninstallService();
                   break;
               default:
                   throw new NotImplementedException();
           }
       }
   }
   

2. 这里是支持代码:

   using System.Collections;
   using System.Configuration.Install;
   using System.ServiceProcess;
   
   private static bool IsInstalled()
   {
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               ServiceControllerStatus status = controller.Status;
           } catch {
               return false;
           }
           return true;
       }
   }
   
   private static bool IsRunning()
   {
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           if (!IsInstalled()) return false;
           return (controller.Status == ServiceControllerStatus.Running);
       }
   }
   
   private static AssemblyInstaller GetInstaller()
   {
       AssemblyInstaller installer = new AssemblyInstaller(
           typeof(YourServiceType).Assembly, null);
       installer.UseNewContext = true;
       return installer;
   }
   

3. 继续支持代码...

   private static void InstallService()
   {
       if (IsInstalled()) return;
   
       try {
           using (AssemblyInstaller installer = GetInstaller()) {
               IDictionary state = new Hashtable();
               try {
                   installer.Install(state);
                   installer.Commit(state);
               } catch {
                   try {
                       installer.Rollback(state);
                   } catch { }
                   throw;
               }
           }
       } catch {
           throw;
       }
   }
   
   private static void UninstallService()
   {
       if ( !IsInstalled() ) return;
       try {
           using ( AssemblyInstaller installer = GetInstaller() ) {
               IDictionary state = new Hashtable();
               try {
                   installer.Uninstall( state );
               } catch {
                   throw;
               }
           }
       } catch {
           throw;
       }
   }
   
   private static void StartService()
   {
       if ( !IsInstalled() ) return;
   
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               if ( controller.Status != ServiceControllerStatus.Running ) {
                   controller.Start();
                   controller.WaitForStatus( ServiceControllerStatus.Running, 
                       TimeSpan.FromSeconds( 10 ) );
               }
           } catch {
               throw;
           }
       }
   }
   
   private static void StopService()
   {
       if ( !IsInstalled() ) return;
       using ( ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               if ( controller.Status != ServiceControllerStatus.Stopped ) {
                   controller.Stop();
                   controller.WaitForStatus( ServiceControllerStatus.Stopped, 
                        TimeSpan.FromSeconds( 10 ) );
               }
           } catch {
               throw;
           }
       }
   }
   

4. 此时，在目标计算机上安装服务后，只需使用 -install 命令行参数从命令行(像任何普通应用程序一样)运行服务即可安装并启动您的服务。

我想我已经涵盖了所有内容，但如果您发现这不起作用，请告诉我，以便我更新答案。
