How to check if executable started as service or from SYSTEM account?

Question

I have a program that can be installed and started as service, or can be started from SYSTEM account using the 'at' command. I need to find a way to know if the executable was started as service or from SYSTEM account, so I could know if I need to call ServiceBase.Run or perform other work at the executable entry point (Main function).

Environment.UserInteractive is false in both situations.

WindowsIdentity.GetCurrent().IsSystem is true in both situations.

I'd like not to pass any command line arguments to solve this.

Entry point's ReflectedType.BaseType.FullName doesn't work either.

The accepted answer on that question looks like it would work for you - it checks whether you're running from ServiceBase or not. — Richard, Mar 27 '15 at 12:28
@Richard well, I tested it out even before asking this question and in an in any situation the BaseType.FullName is System.Object... — user2102508, Mar 27 '15 at 12:31
Using a command line argument is simple and easy to understand and maintain. You can add a `-service` argument when you install the service. — Martin Liversage, Mar 27 '15 at 12:33

You could try looking at the parent of your process.

public static bool IsRunningAsService() 
{
    return Process.GetCurrentProcess().Parent().ProcessName == "services";
}
