{
   public static void Main()
   {
      string[] values = { "123456789", "12345.6789", "12 345,6789",
                          "123,456.789", "123 456,789", "123,456,789.0123",
                          "123 456 789,0123" };
      CultureInfo[] cultures = { new CultureInfo("en-US"),
                                 new CultureInfo("fr-FR") }; 

      foreach (CultureInfo culture in cultures)
      {
         Console.WriteLine("String -> Decimal Conversion Using the {0} Culture",
                           culture.Name);
         foreach (string value in values)
         {
            Console.Write("{0,20}  ->  ", value);
            try {
               Console.WriteLine(Convert.ToDecimal(value, culture));
            }
            catch (FormatException) {
               Console.WriteLine("FormatException");
            }
         }
         Console.WriteLine();
      }                     
   }
