Ejemplos

En el ejemplo de código siguiente se muestra la información de dirección DHCP de las interfaces de red en el equipo local.

void DisplayDhcpServerAddresses()
{
   Console::WriteLine( "DHCP Servers" );
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum19 = adapters->GetEnumerator();
   while ( myEnum19->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum19->Current);
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
      IPAddressCollection ^ addresses = adapterProperties->DhcpServerAddresses;
      if ( addresses->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
         System::Collections::IEnumerator^ myEnum20 = addresses->GetEnumerator();
         while ( myEnum20->MoveNext() )
         {
            IPAddress^ address = safe_cast<IPAddress^>(myEnum20->Current);
            Console::WriteLine( "  Dhcp Address ............................ : {0}", 
               address );
         }
         Console::WriteLine();
      }
   }
}

    foreach (NetworkInterface adapter in adapters)

            }
            Console.WriteLine();

Comentarios

El Protocolo de configuración dinámica de host (DHCP) permite a un equipo obtener una dirección de red de un servidor DHCP, en lugar de usar una dirección de red estática (fija). Un servidor DHCP no asigna permanentemente direcciones; en su lugar, usa temporalmente una de varias direcciones disponibles para el equipo.
