.NET：给定服务名称，如何获取 Process 对象？

Question

给定一个服务名称（例如SNMPTRAP）我怎样才能得到一个System.Diagnostics.Process 对象？

到目前为止，我已经找到了 System.ServiceProcess.ServiceController 类和 System.Diagnostics.Process 类，但似乎无法从中得到一个。

看起来 WMI 无需借助 interop/Win32 即可工作。下面是一个概念验证：

    private static Process ProcessFromServiceName(string serviceName)
    {
        // Note abuse of foreach as a lazy way of getting first item.
        // Also assumes that the first service in the collection is the correct one.

        string queryText = String.Format(   CultureInfo.InvariantCulture,
                                            "SELECT * FROM Win32_Service WHERE Name='{0}'",
                                            serviceName);
        var query = new SelectQuery(queryText);
        var searcher = new ManagementObjectSearcher(query);
        foreach (ManagementObject service in searcher.Get())
        {
            int processId = (int)(uint)service.Properties["ProcessId"].Value;
            Process process = Process.GetProcessById(processId);
            return process;
        }
        return null;
    }
