How do I configure the name of a Windows service upon installation (or easily at compile time)?
提问by Rune
I've created a Windows service in C#, installed it on a server and it is running fine.
我在 C# 中创建了一个 Windows 服务，将其安装在服务器上并且运行良好。
Now I want to install the same service again, but running from a different working directory, having a different config file etc. Thus, I would like to have two(or more) instances of the same service running simultaneously. Initially, this isn't possible since the installer will complain that there's already a service with the given name installed.
现在我想再次安装相同的服务，但从不同的工作目录运行，具有不同的配置文件等。因此，我希望同时运行同一服务的两个（或更多）实例。最初，这是不可能的，因为安装程序会抱怨已经安装了具有给定名称的服务。
I can overcome this by changing my code, setting the ServiceBase.ServiceNameproperty to a new value, then recompiling and running InstallUtil.exe again. However, I would much prefer if I could set the service name at install-time, i.e. ideally I would do something like
我可以通过更改我的代码，将ServiceBase.ServiceName属性设置为新值，然后重新编译并再次运行 InstallUtil.exe来克服这个问题。但是，如果我可以在安装时设置服务名称，我会更喜欢，即理想情况下我会做类似的事情
InstallUtil.exe /i /servicename="MyService Instance 2" MyService.exe
InstallUtil.exe /i /servicename="MyService Instance 2" MyService.exe
If this isn't achievable (I very much doubt it), I would like to be able to inject the service name when I build the service. I thought it might be possible to use some sort of build event, use a clever msbuild or nant trick or something along those lines, but I haven't got a clue.
如果这无法实现（我非常怀疑），我希望能够在构建服务时注入服务名称。我认为可能可以使用某种构建事件，使用聪明的 msbuild 或 nant 技巧或类似的东西，但我没有任何线索。
Any suggestions would be greatly appreciated.
任何建议将不胜感激。
Thank you for your time.
感谢您的时间。

I tried accessing a configuration using
我尝试使用访问配置
ConfigurationManager.OpenExeConfiguration(string exePath)
in the installer, but couldn't get it to work.
在安装程序中，但无法使其工作。
Instead I decided to use System.Environment.GetCommandLineArgs()in the installer like this:
相反，我决定System.Environment.GetCommandLineArgs()在安装程序中像这样使用：
string[] commandlineArgs = Environment.GetCommandLineArgs();
string servicename;
string servicedisplayname;
ParseServiceNameSwitches(
commandlineArgs,
out servicename,
out servicedisplayname);
serviceInstaller.ServiceName = servicename;
serviceInstaller.DisplayName = servicedisplayname;
Now I can install my services using
现在我可以使用安装我的服务
InstallUtil.exe /i InstallableService.dll /servicename="myserviceinstance_2" /servicedisplayname="My Service Instance 2"
InstallUtil.exe /i InstallableService.dll /servicename="myserviceinstance_2" /servicedisplayname="我的服务实例 2"
I wrote up a more elaborate explanation here.
我在这里写了一个更详细的解释。

You can't pass this in as a command line arg, since InstallUtil doesn't provide the right hooks for that.
您不能将其作为命令行参数传递，因为 InstallUtil 没有为此提供正确的挂钩。
However, you can make your service installer read the ServiceName from a config file. If you look at some codefor a typical ServiceInstaller, you'll see it's just a matter of having the appropriate DisplayName and ServiceName properties setup at runtime. These could easily be read from a configuration file instead of being hard-coded.
但是，您可以让服务安装程序从配置文件中读取 ServiceName。如果您查看典型 ServiceInstaller 的一些代码，您会发现这只是在运行时设置适当的 DisplayName 和 ServiceName 属性的问题。这些可以很容易地从配置文件中读取，而不是硬编码。

Instead of using Environment.GetCommandLineArgs();the class Installerhas a property called Contextfrom which you can access command line arguments passed to InstallUtil structured in a nice StringDictionary.
而不是使用具有调用的属性Environment.GetCommandLineArgs();的类，您可以从中访问传递给 InstallUtil 的命令行参数，该参数以一个 nice .InstallerContextStringDictionary
