Testing application for Administrative Running Rights

Question

I want a sure-shot method to test if the application was run via the UAC box and has full administrative rights. Earlier, I thought of making a folder in C:\Windows\ for testing but running it on other computers proved to be a failure!

The UAC box provides all administrative rights to the computer to do anything(including making folders and creating files in places which needs there rights) and also makes sure that any child program so called or created also does have the same rights as the parent.

Is there a sure-shot way to test if my application has been provided all the administrative rights that I can maximum get by the user while running the application or not? If yes, I would be glad to have to piece of code-work!

C#:

using System.Security.Principal;

...

var identity = WindowsIdentity.GetCurrent();
var principal = new WindowsPrincipal(identity);
bool isElevated = principal.IsInRole(WindowsBuiltInRole.Administrator);

VB.Net:

Imports System.Security.Principal

...

Dim identity = WindowsIdentity.GetCurrent()
Dim principal = new WindowsPrincipal(identity)
Dim isElevated as Boolean = principal.IsInRole(WindowsBuiltInRole.Administrator)
