我认为这取决于你使用的操作系统，Vista很难附加到服务，因为会话之间的分离。

我过去使用的两个选项是:

Use GFlags (in the Debugging Tools for Windows) to setup a permanent debugger for a process. This exists in the "Image File Execution Options" registry key and is incredibly useful. I think you'll need to tweak the Service settings to enable "Interact with Desktop". I use this for all types of debugging, not just services. The other option, is to separate the code a bit, so that the service part is interchangable with a normal app startup. That way, you can use a simple command line flag, and launch as a process (rather than a Service), which makes it much easier to debug.

希望这能有所帮助。

有时，分析在服务启动期间发生了什么是很重要的。附加到流程在这里没有帮助，因为在服务启动时附加调试器的速度不够快。

简单的回答是，我使用以下4行代码来做到这一点:

#if DEBUG
    base.RequestAdditionalTime(600000); // 600*1000ms = 10 minutes timeout
    Debugger.Launch(); // launch and attach debugger
#endif

这些被插入到服务的OnStart方法中，如下所示:

protected override void OnStart(string[] args)
{
    #if DEBUG
       base.RequestAdditionalTime(600000); // 10 minutes timeout for startup
       Debugger.Launch(); // launch and attach debugger
    #endif
    MyInitOnstart(); // my individual initialization code for the service
    // allow the base class to perform any work it needs to do
    base.OnStart(args);
}

对于那些以前没有做过的人，我在下面列出了详细的提示，因为你很容易陷入困境。以下提示适用于Windows 7x64和Visual Studio 2010 Team Edition，但也适用于其他(更新的)环境。

重要提示:以“手动”模式部署服务(在VS命令提示符中使用InstallUtil实用程序或运行您准备好的服务安装程序项目)。在启动服务之前打开Visual Studio并加载包含服务源代码的解决方案——在Visual Studio中根据需要设置额外的断点——然后通过服务控制面板启动服务。

因为调试器。启动代码，这将导致一个对话框“一个未处理的Microsoft . net Framework异常发生在Servicename.exe.”出现。单击“是”，调试Servicename.exe，如下图所示:

之后，Windows UAC可能会提示您输入管理凭据。输入它们并继续执行Yes:

之后，著名的Visual Studio即时调试器窗口出现。它询问您是否要使用已删除的调试器进行调试。在单击Yes之前，选择不想打开新实例(第二个选项)——在这里，新实例没有帮助，因为不会显示源代码。所以你选择之前打开的Visual Studio实例:

单击Yes后，过一会儿Visual Studio将在调试器所在的行中显示黄色箭头。启动语句，您可以调试您的代码(方法MyInitOnStart，其中包含初始化)。

按F5继续立即执行，直到到达您准备的下一个断点。

提示:要保持服务运行，请选择Debug -> Detach all。这允许您在服务正确启动并完成调试启动代码之后运行与服务通信的客户机。如果您按下Shift+F5(停止调试)，这将终止服务。您应该使用服务控制面板来停止它，而不是这样做。

请注意,

If you build a Release, then the debug code is automatically removed and the service runs normally. I am using Debugger.Launch(), which starts and attaches a debugger. I have tested Debugger.Break() as well, which did not work, because there is no debugger attached on start up of the service yet (causing the "Error 1067: The process terminated unexpectedly."). RequestAdditionalTime sets a longer timeout for the startup of the service (it is not delaying the code itself, but will immediately continue with the Debugger.Launch statement). Otherwise the default timeout for starting the service is too short and starting the service fails if you don't call base.Onstart(args) quickly enough from the debugger. Practically, a timeout of 10 minutes avoids that you see the message "the service did not respond..." immediately after the debugger is started. Once you get used to it, this method is very easy because it just requires you to add 4 lines to an existing service code, allowing you quickly to gain control and debug.

使用TopShelf库。

创建一个控制台应用程序，然后在Main中配置安装

class Program
    {
        static void Main(string[] args)
        {
            HostFactory.Run(x =>
            {

                // setup service start and stop.
                x.Service<Controller>(s =>
                {
                    s.ConstructUsing(name => new Controller());
                    s.WhenStarted(controller => controller.Start());
                    s.WhenStopped(controller => controller.Stop());
                });

                // setup recovery here
                x.EnableServiceRecovery(rc =>
                {
                    rc.RestartService(delayInMinutes: 0);
                    rc.SetResetPeriod(days: 0);
                });

                x.RunAsLocalSystem();
            });
        }
}

public class Controller
    {
        public void Start()
        {

        }

        public void Stop()
        {

        }
    }

要调试您的服务，只需在visual studio中按F5。

要安装服务，键入cmd "console.exe install"

然后，您可以在windows服务管理器中启动和停止服务。

我也认为为正常执行和作为服务提供一个单独的“版本”是可行的，但真的需要为此目的专门提供一个单独的命令行开关吗?

你就不能这样做吗:

public static int Main(string[] args)
{
  if (!Environment.UserInteractive)
  {
    // Startup as service.
  }
  else
  {
    // Startup as application
  }
}

这将有“好处”，你可以通过双击启动你的应用程序(好吧，如果你真的需要的话)，你可以在Visual Studio中点击F5(不需要修改项目设置，包括/控制台选项)。

严格来说，是环境。UserInteractive检查是否为当前窗口站设置了WSF_VISIBLE标志，但是除了作为(非交互式)服务运行之外，还有其他原因它将返回false吗?

当我几周前建立一个新的服务项目时，我发现了这个帖子。虽然有很多很好的建议，但我仍然没有找到我想要的解决方案:在不修改服务类的情况下调用服务类的OnStart和OnStop方法的可能性。

我想到的解决方案是利用环境。交互式选择运行模式，正如这篇文章的其他答案所建议的。

static void Main()
{
    ServiceBase[] servicesToRun;
    servicesToRun = new ServiceBase[] 
    {
        new MyService()
    };
    if (Environment.UserInteractive)
    {
        RunInteractive(servicesToRun);
    }
    else
    {
        ServiceBase.Run(servicesToRun);
    }
}

RunInteractive helper使用反射来调用受保护的OnStart和OnStop方法:

static void RunInteractive(ServiceBase[] servicesToRun)
{
    Console.WriteLine("Services running in interactive mode.");
    Console.WriteLine();

    MethodInfo onStartMethod = typeof(ServiceBase).GetMethod("OnStart", 
        BindingFlags.Instance | BindingFlags.NonPublic);
    foreach (ServiceBase service in servicesToRun)
    {
        Console.Write("Starting {0}...", service.ServiceName);
        onStartMethod.Invoke(service, new object[] { new string[] { } });
        Console.Write("Started");
    }

    Console.WriteLine();
    Console.WriteLine();
    Console.WriteLine(
        "Press any key to stop the services and end the process...");
    Console.ReadKey();
    Console.WriteLine();

    MethodInfo onStopMethod = typeof(ServiceBase).GetMethod("OnStop", 
        BindingFlags.Instance | BindingFlags.NonPublic);
    foreach (ServiceBase service in servicesToRun)
    {
        Console.Write("Stopping {0}...", service.ServiceName);
        onStopMethod.Invoke(service, null);
        Console.WriteLine("Stopped");
    }

    Console.WriteLine("All services stopped.");
    // Keep the console alive for a second to allow the user to see the message.
    Thread.Sleep(1000);
}

这是所需的所有代码，但我还编写了带有解释的演练。
