Beispiele

Im folgenden Codebeispiel wird überprüft, ob eine Netzwerkschnittstelle IPv4 unterstützt.The following code example checks whether a network interface supports IPv4.

void DisplayIPv4NetworkInterfaces()
{
   array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   Console::WriteLine( "IPv4 interface information for {0}.{1}", properties->HostName, properties->DomainName );
   System::Collections::IEnumerator^ myEnum23 = nics->GetEnumerator();
   while ( myEnum23->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum23->Current);

      // Only display informatin for interfaces that support IPv4.
      if ( adapter->Supports( NetworkInterfaceComponent::IPv4 ) == false )
      {
         continue;
      }
      Console::WriteLine();
      Console::WriteLine( adapter->Description );

      // Underline the description.
      Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();

      // Try to get the IPv4 interface properties.
      IPv4InterfaceProperties ^ p = adapterProperties->GetIPv4Properties();
      if ( !p )

Hinweise

Die Werte in dieser Enumeration werden verwendet, durch die Supports Methode, um von einer Netzwerkschnittstelle unterstützt Internet Protocol, Version anzugeben.The values in this enumeration are used by the Supports method to specify the Internet Protocol version supported by a network interface.
