Examples

The following example demonstrates the effect of changing the NumberGroupSeparator 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->NumberGroupSeparator = " ";
   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.NumberGroupSeparator = " ";
      Console.WriteLine( myInt.ToString( "N", nfi ) );
   }
}

Remarks

The NumberGroupSeparator property is used with the "N" standard format string to define the symbol that separates groups of integral digits. For more information, see Standard Numeric Format Strings.

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