How do I retrieve the username that a Windows service is running under?

Given a service name, I would like to retrieve the username that it runs under (i.e. the username shown in the 'Log On' tab of a service's properties window).

There doesn't appear to be anything in the ServiceController class to retrieve this basic information. Nothing e开发者_Python百科lse in System.ServiceProcess looks like it exposes this information either.

Is there a managed solution to this, or am I going to have to drop down into something lower-level?

Using WMI, with the System.Management you can try the following code:

using System;
namespace WindowsServiceTest
{
    class Program
    {
        static void Main(string[] args)
        {
            System.Management.SelectQuery sQuery = new System.Management.SelectQuery(string.Format("select name, startname from Win32_Service")); // where name = '{0}'", "MCShield.exe"));
            using (System.Management.ManagementObjectSearcher mgmtSearcher  = new System.Management.ManagementObjectSearcher(sQuery))
            {
                foreach (System.Management.ManagementObject service in mgmtSearcher.Get())
                {
                    string servicelogondetails =
                        string.Format("Name: {0} ,  Logon : {1} ", service["Name"].ToString(), service["startname"]).ToString();
                    Console.WriteLine(servicelogondetails);
                }
            }
            Console.ReadLine();
        }
    }
}

You can then later substitute the commented code with your service name, and it should only return the instances of your service process that is running.

WMI is your friend. Look at Win32_Service, specifically the StartName property. You can access WMI from C# via the System.Management.ManagementClass.

If you've not used WMI before, this article seems to be quite a good tutorial.

You can find this using the Windows Registry, reading the following string value, replacing [SERVICE_NAME] with the name of the Windows Service:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\[SERVICE_NAME]\ObjectName

Try this:

System.Security.Principal.WindowsIdentity.GetCurrent();

but the most obvious you will get LOCAL SYSTEM or NETWORK. The reason that you cannot show this user - that service can manage multiple users (shared by desktop, attached to current windows session, using shared resource ...) System starts service, but any user can use it.

This solution works fine for me:

    ManagementObject wmiService = new ManagementObject("Win32_Service.Name='" + this.ServiceName + "'");
    wmiService.Get();
    string user = wmiService["startname"].ToString();

    public String getUsername() {
    string username = null;
    try {
      ManagementScope ms = new ManagementScope("\\\\.\\root\\cimv2");
      ms.Connect();
      ObjectQuery query = new ObjectQuery
              ("SELECT * FROM Win32_ComputerSystem");
      ManagementObjectSearcher searcher =
              new ManagementObjectSearcher(ms, query);
      foreach (ManagementObject mo in searcher.Get()) {
        username = mo["UserName"].ToString();
      }
      string[] usernameParts = username.Split('\\');
      username = usernameParts[usernameParts.Length - 1];
    } catch (Exception) {
      username = "SYSTEM";
    }
    return username;
  }
