// and " " as the decimal separator.
value = "19 694,00";
style = NumberStyles.AllowDecimalPoint | NumberStyles.AllowThousands;
provider = new CultureInfo("fr-FR");
number = Int16.Parse(value, style, provider);
Console.WriteLine("'{0}' converted to {1}.", value, number);
// Displays:
// '19 694,00' converted to 19694.
try
