Windows服务如何确定它的服务名称？ [英] How can a Windows Service determine its ServiceName?

问题描述

我已经看了，但没有找到什么应该是一个简单的问题：

I've looked and couldn't find what should be a simple question:

如何可以在Windows服务决定它启动的服务名称？

我知道安装可以在注册表破解并添加命令行参数，但逻辑上这似乎是它的应的是不必要的，因此这个问题。

I know the installation can hack at the registry and add a command line argument, but logically that seems like it should be unnecessary, hence this question.

我希望能比注册表破解更干净运行单个二进制文件的多个副本。

I'm hoping to run multiple copies of a single binary more cleanly than the registry hack.

修改

这是用C＃。我的应用程序的的Main（）的切入点，做不同的事情，这取决于
命令行参数：

This is written in C#. My apps Main() entry point does different things, depending on command line arguments:

• 安装或卸载该服务。命令行可以提供一个非默认
  服务名称并能改变工作线程的数量。


• （调试）运行作为命令行可执行文件，


• 运行作为Windows服务。在这里，它创造了我的 ServiceBase 的衍生实例
  类，然后调用的 System.ServiceProcess.ServiceBase.Run（实例）; 的

• Install or Uninstall the service. The command line can provide a non-default ServiceName and can change the number of worker threads.
• Run as a command-line executable (for debugging),
• Run as a "Windows Service". Here, it creates an instance of my ServiceBase-derived class, then calls System.ServiceProcess.ServiceBase.Run(instance);

目前，安装一步附加的服务名称和线程数到的的ImagePath 的注册表，以便应用程序能确定它的服务名称。

Currently, the installation step appends the service name and thread count to the ImagePath in the registry so the app can determine it's ServiceName.

下面是一个WMI的解决方案。重写的 ServiceBase.ServiceMainCallback（）的也可以工作，但是这似乎为我工作...

Here is a WMI solution. Overriding the ServiceBase.ServiceMainCallback() might also work, but this seems to work for me...

    protected String GetServiceName()
    {
        // Calling System.ServiceProcess.ServiceBase::ServiceNamea allways returns
        // an empty string,
        // see https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=387024

        // So we have to do some more work to find out our service name, this only works if
        // the process contains a single service, if there are more than one services hosted
        // in the process you will have to do something else

        int processId = System.Diagnostics.Process.GetCurrentProcess().Id;
        String query = "SELECT * FROM Win32_Service where ProcessId = " + processId;
        System.Management.ManagementObjectSearcher searcher =
            new System.Management.ManagementObjectSearcher(query);

        foreach (System.Management.ManagementObject queryObj in searcher.Get()) {
            return queryObj["Name"].ToString();
        }

        throw new Exception("Can not get the ServiceName");
    }
