一个Windows服务中的多个服务进程（System.ServiceProcess.ServiceBase） [英] Multiple service processes (System.ServiceProcess.ServiceBase) in one Windows Service

问题描述

我有两个服务流程（源自 System.ServiceProcess.ServiceBase ）
MyService1 和 MyService2 。

I've got two service processes (derived from System.ServiceProcess.ServiceBase) MyService1 and MyService2.

我正在尝试在 Main（）中运行它们 Windows服务的 Programm.cs 。

I'm trying to run them both in the Main() of a Windows Service's Programm.cs.

static void Main()
    {
        ServiceBase[] servicesToRun = { new MyService1(), new MyService2() };
        ServiceBase.Run(servicesToRun);
    }

在 OnStart 我将 MyService1 和 MyService2 的方法写入日志文件，以便告诉它们正在运行。

In the OnStart methods of both MyService1 and MyService2 I write to a log file so I can tell they are running.

系统正常运行，我可以安装服务。

The system builds fine and I can install the service.

但只有 MyService1 运行。 MyService2 不执行任何操作（即没有启动日志条目）。当我更改数组中的顺序时：

But only MyService1 runs. MyService2 doesn't do a thing (i.e. no start-up log entry). When I change the order in the array:

ServiceBase[] servicesToRun = { new MyService2(), new MyService1() }

仅运行 MyService2 。

要尝试深入了解这一点，我使用了一个小工具AndersonImes.ServiceProcess.ServicesLoader（ https://windowsservicehelper.codeplex.com/ ）来解决无法在Visual Studio中直接调试Windows服务的限制。使用此工具，我可以使两个服务 MyService1 和 MyService2 相互启动并运行。但是我仍然不知道为什么Windows仅运行 ServiceBase [] servicesToRun 数组中的第一项。

To try to get to the bottom of this, I'm using a little tool AndersonImes.ServiceProcess.ServicesLoader (https://windowsservicehelper.codeplex.com/) to get around the limitation that you cannot directly debug a windows service in Visual Studio. With this tool I can get both services MyService1 and MyService2 to start and run next to each other. But I still don't know why Windows is running only the first item in the ServiceBase[] servicesToRun array.

有任何想法吗？

关于ServicesDependedOn的解释与我在项目中看到的并不完全匹配。这不是要启动它们，而是要确保它们已启动。查看 https：/ /msdn.microsoft.com/zh-CN/library/system.serviceprocess.servicecontroller.servicesdependedon%28v=vs.110%29.aspx 。我不需要这个，因为它们彼此不依赖。

The explanation there around ServicesDependedOn isn't quite matching what I see in my project though. It's not about starting them but making sure they are started. Check out https://msdn.microsoft.com/en-us/library/system.serviceprocess.servicecontroller.servicesdependedon%28v=vs.110%29.aspx as well. I don't need this because they do not depend on each other.
