Exemplos

O exemplo de código a seguir exibe as informações de endereço DHCP para os adaptadores de rede no computador 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 );

Comentários

O DHCP (Dynamic Host Configuration Protocol) permite que um computador obtenha um endereço de rede de um servidor DHCP, em vez de usar um endereço de rede estático (fixo). Um servidor DHCP não atribui permanentemente endereços; em vez disso, ele usa temporariamente um dos vários endereços disponíveis para o computador.
