instance.NumberGroupSeparator = value

public string NumberGroupSeparator { get; set; }

public:
property String^ NumberGroupSeparator {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_NumberGroupSeparator ()

/** @property */
public void set_NumberGroupSeparator (String value)

public function get NumberGroupSeparator () : String

public function set NumberGroupSeparator (value : String)

Imports System.Globalization

Class NumberFormatInfoSample

   Public Shared Sub Main()

      ' Gets a NumberFormatInfo associated with the en-US culture.
      Dim nfi As NumberFormatInfo = New CultureInfo("en-US", False).NumberFormat

      ' Displays a value with the default separator (",").
      Dim myInt As Int64 = 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))

   End Sub 'Main
