Ejemplos

En el ejemplo siguiente se usa la AddressList propiedad para tener acceso a las direcciones IP asociadas a IPHostEntry.

void GetIpAddressList( String^ hostString )
{
   try
   {
      // Get 'IPHostEntry' object containing information
      // like host name, IP addresses, aliases for a host.
      IPHostEntry^ hostInfo = Dns::GetHostByName( hostString );
      Console::WriteLine( "Host name : {0}", hostInfo->HostName );
      Console::WriteLine( "IP address List : " );
      for ( int index = 0; index < hostInfo->AddressList->Length; index++ )
         Console::WriteLine( hostInfo->AddressList[ index ] );
   }
   catch ( SocketException^ e ) 
   {
      Console::WriteLine( "SocketException caught!!!" );
