C# administrator privilege - checking

This will return a bool valid

using System.Security.Principal;

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

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);
