Field Value

Examples

The following code example displays the value of the current host's None address in standard compressed format.

// This method displays the value of the current host's None address in
// standard compressed format. The None address is used by the host to disable
// listening to client activities on all the interfaces.
void displayIPv6NoneAddress()
{
   try
   {
      // Get the None address.
      IPAddress^ none = IPAddress::IPv6None;
      
      // Transform the None address to a string using the overloaded
      // ToString() method. Note that the resulting string is in the compact
      // form: "::".
      String^ ipv6None = none->ToString();

      Console::WriteLine( "The IPv6 None address is: {0}", ipv6None );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "->Item[displayIPv6NoneAddress] Exception: {0}", e );
   }
}

// This method displays the value of the current host's None address in  
// standard compressed format. The None address is used by the host to disable
// listening to client activities on all the interfaces.
private static void displayIPv6NoneAddress()
{
  try
  {
    
    // Get the None address.
    IPAddress none  = IPAddress.IPv6None;

    // Transform the None address to a string using the overloaded
    // ToString() method. Note that the resulting string is in the compact 
    // form: "::".
    string ipv6None = none.ToString();

    Console.WriteLine("The IPv6 None address is: " + ipv6None);
  }
  catch (Exception e) 
  {
    Console.WriteLine("[displayIPv6NoneAddress] Exception: " + e.ToString());
  }
}

' This function prints the value of the current host's None address in  
' standard compressed format. The None address is used by the host to disable
' listening to client activities on all the interfaces.
Private Shared Sub printIPv6NoneAddress()
   Try
      
      ' Get the None address.
      Dim none As IPAddress = IPAddress.IPv6None
      
      ' Transform the None address to a string using the overloaded
      ' ToString() method. Note that the resulting string is in the compact 
      ' form: "::".
      Dim ipv6None As String = none.ToString()
      
      Console.WriteLine(("The IPv6 None address is: " + ipv6None))
   Catch e As Exception
      Console.WriteLine(("[printIPv6NoneAddress] Exception: " + e.ToString()))
   End Try
End Sub

Remarks

The Socket.Bind method uses the IPv6None field to indicate that a Socket must not listen for client activity. The IPv6None field is equivalent to 0:0:0:0:0:0:0:0 in colon-hexadecimal notation, or to ::0 in compact notation.
