Examples

The following example demonstrates the effect of changing the NumberDecimalSeparator property.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // 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
*/

using System;
using System.Globalization;

class NumberFormatInfoSample {

   public static void Main() {

      // Gets a NumberFormatInfo associated with the en-US culture.
      NumberFormatInfo nfi = new CultureInfo( "en-US", false ).NumberFormat;

      // Displays a value with the default separator (".").
      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 ) );
   }
}


/*

      Dim myInt As Int64 = 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))

Remarks

The NumberDecimalSeparator property is used with the "E", "F", "G", "N", and "R" standard format strings to define the symbol that separates integral from fractional digits. For more information, see Standard Numeric Format Strings.

The initial value of this property is derived from the settings in the Region and Language item in Control Panel.
