Пример

В следующем примере показано, как получить NumberFormatInfo объект для соответствующего CultureInfo объекта и использовать полученный объект для запроса сведений о форматировании чисел для конкретного языка и региональных параметров.

using System;
using System.Globalization;
using System.Text;

public sealed class App
{
    static void Main()
    {
        StringBuilder sb = new StringBuilder();

        // Loop through all the specific cultures known to the CLR.
        foreach (CultureInfo ci in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
        {
            // Only show the currency symbols for cultures that speak English.
            if (ci.TwoLetterISOLanguageName != "en") continue;

            // Display the culture name and currency symbol.
            NumberFormatInfo nfi = ci.NumberFormat;
            sb.AppendFormat("The currency symbol for '{0}' is '{1}'",
                ci.DisplayName, nfi.CurrencySymbol);
            sb.AppendLine();
        }
        Console.WriteLine(sb.ToString());
    }
}

// This code produces the following output.
//
// The currency symbol for 'English (United States)' is '$'
// The currency symbol for 'English (United Kingdom)' is '£'
// The currency symbol for 'English (Australia)' is '$'

Public Module Example
   Public Sub Main() 
      Dim sb As New StringBuilder()

      ' Loop through all the specific cultures known to the CLR.
      For Each ci In CultureInfo.GetCultures(CultureTypes.SpecificCultures) 
         ' Only show the currency symbols for cultures that speak English.
         If ci.TwoLetterISOLanguageName <> "en" Then Continue For

         ' Display the culture name and currency symbol.
         Dim nfi As NumberFormatInfo = ci.NumberFormat
         sb.AppendFormat("The currency symbol for '{0}' is '{1}'",
                         ci.DisplayName, nfi.CurrencySymbol)
         sb.AppendLine()
      Next
      Console.WriteLine(sb.ToString())
   End Sub
