In .NET/C# test if process has administrative privileges

Question

Is there a canonical way to test to see if the process has administrative privileges on a machine?

I\'m going to be starting a long running process, and much later

Answer 1

What about:

using System.Runtime.InteropServices;

internal static class Useful {
    [DllImport("shell32.dll", EntryPoint = "IsUserAnAdmin")]
    public static extern bool IsUserAnAdministrator();
}
