Check if the current user is administrator

Question

My application need to run some scripts, and I must be sure that the administrator is running them... what is the best way doing it using C#?

Answer 1

Using WindowsPrincipal:

public static bool IsAdministrator()
{
    WindowsIdentity identity = WindowsIdentity.GetCurrent();
    WindowsPrincipal principal = new WindowsPrincipal(identity);
    return principal.IsInRole(WindowsBuiltInRole.Administrator);
}

Answer 2

return new WindowsPrincipal(WindowsIdentity.GetCurrent())
    .IsInRole(WindowsBuiltInRole.Administrator);
