using System.Collections.Generic;
using System.Text;
using System.Globalization;

class Program {
    static void Main(string[] args) {
        CultureInfo ci = new CultureInfo("de-AT-ST");
        System.Threading.Thread.CurrentThread.CurrentCulture = ci;
        System.Threading.Thread.CurrentThread.CurrentUICulture = ci;

using System.Threading;
class MainClass

    Console.WriteLine(Thread.CurrentThread.CurrentUICulture.Name);
  }
}
