Nilai Properti

IPAddressCollection

Yang IPAddressCollection berisi informasi alamat untuk server DHCP, atau array kosong jika tidak ada server yang ditemukan.

Atribut: UnsupportedOSPlatformAttribute

Contoh

Contoh kode berikut menampilkan informasi alamat DHCP untuk antarmuka jaringan di komputer lokal.

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);

Keterangan

Dynamic Host Configuration Protocol (DHCP) memungkinkan komputer untuk mendapatkan alamat jaringan dari server DHCP, dibandingkan dengan menggunakan alamat jaringan statis (tetap). Server DHCP tidak menetapkan alamat secara permanen; sebaliknya, ia untuk sementara menggunakan salah satu dari sejumlah alamat yang tersedia ke komputer.
