Check for administrator privileges in C#

Question

I want to know if a program is running as administrator.

The user doesn't have to be administrator. I only want to know if my application has rights to edit some secured files that are editable when running as Administrator.

Answer 1

Here's @atrljoe's answer turned into a one liner using the latest C#:

using System.Security.Principal;

static bool IsElevated => new WindowsPrincipal(WindowsIdentity.GetCurrent()).IsInRole(WindowsBuiltInRole.Administrator);
