Przykłady

Poniższy przykład kodu przedstawia adresy DNS dla interfejsów sieciowych na komputerze lokalnym.

void DisplayDnsAddresses()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum11 = adapters->GetEnumerator();
   while ( myEnum11->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum11->Current);
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
      IPAddressCollection ^ dnsServers = adapterProperties->DnsAddresses;
      if ( dnsServers->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
         System::Collections::IEnumerator^ myEnum12 = dnsServers->GetEnumerator();
         while ( myEnum12->MoveNext() )
         {
            IPAddress ^ dns = safe_cast<IPAddress ^>(myEnum12->Current);
            Console::WriteLine( "  DNS Servers ............................. : {0}", 
               dns->ToString());
         }
      }
   }
}

    foreach (NetworkInterface adapter in adapters)
    {

        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();

                    dns.ToString());
            }
            Console.WriteLine();
        }
    }
}
Public Shared Sub DisplayDnsAddresses()

            Dim dns As IPAddress
            For Each dns In  dnsServers
                Console.WriteLine("  DNS Servers ............................. : {0}",dns.ToString() )
            Next dns
        End If
    Next adapter

End Sub

Uwagi

DNS to hierarchiczny system nazewnictwa używany do mapowania nazw hostów na adresy IP.
