   // Gets a NumberFormatInfo associated with the en-US culture.
   CultureInfo^ MyCI = gcnew CultureInfo( "en-US",false );
   NumberFormatInfo^ nfi = MyCI->NumberFormat;
   
   // Displays a value with the default separator (S".").
   Int64 myInt = 123456789;
   Console::WriteLine( myInt.ToString( "N", nfi ) );
   
   // Displays the same value with a blank as the separator.
   nfi->NumberDecimalSeparator = " ";
   Console::WriteLine( myInt.ToString( "N", nfi ) );
}

/*
This code produces the following output.
123, 456, 789.00
123, 456, 789 00
*/

import System.*;
import System.Globalization.*;

class NumberFormatInfoSample
{
    public static void main(String[] args)
    {
        // Gets a NumberFormatInfo associated with the en-US culture.
        NumberFormatInfo nfi = 
            (new CultureInfo("en-US", false)).get_NumberFormat();
        // Displays a value with the default separator (".").
        Int64 myInt = (Int64)123456789;
        Console.WriteLine(myInt.ToString("N", nfi));
        // Displays the same value with a blank as the separator.
        nfi.set_NumberDecimalSeparator(" ");
        Console.WriteLine(myInt.ToString("N", nfi));
    } //main 
} //NumberFormatInfoSample
