Detect if code is running as a service

Is there a way for an .NET library to detect whether or not it is being run as a service?

Seems I am bit late to the party, but topic seems popular. Interesting difference when run as a service is that at app start current folder points to system directory (C:\windows\system32 by default). Its hardly unlikely user app will start from the system folder in any real life situation.

So, I use following trick (c#):

protected static bool IsRunAsService()
{
    string CurDir = Directory.GetCurrentDirectory();
    if (CurDir.Equals(Environment.SystemDirectory, StringComparison.CurrentCultureIgnoreCase))
    { 
         return true; 
    }

    return (false);
}
