Keterangan

Kelas ini merangkum data untuk antarmuka jaringan, juga dikenal sebagai adaptor, di komputer lokal. Anda tidak membuat instans kelas ini; GetAllNetworkInterfaces metode mengembalikan array yang berisi satu instans kelas ini untuk setiap antarmuka jaringan di komputer lokal.

Konstruktor

NetworkInterface()

Menginisialisasi instans baru kelas NetworkInterface.

Properti

Description	Mendapatkan deskripsi antarmuka.
Id	Mendapatkan pengidentifikasi adaptor jaringan.
IPv6LoopbackInterfaceIndex	Mendapatkan indeks antarmuka loopback IPv6.
IsReceiveOnly	Boolean Mendapatkan nilai yang menunjukkan apakah antarmuka jaringan diatur ke hanya menerima paket data.
LoopbackInterfaceIndex	Mendapatkan indeks antarmuka loopback IPv4.
Name	Mendapatkan nama adaptor jaringan.
NetworkInterfaceType	Mendapatkan jenis antarmuka.
OperationalStatus	Mendapatkan status operasional koneksi jaringan saat ini.
Speed	Mendapatkan kecepatan antarmuka jaringan.
SupportsMulticast	Boolean Mendapatkan nilai yang menunjukkan apakah antarmuka jaringan diaktifkan untuk menerima paket multicast.

Metode

GetAllNetworkInterfaces()	Mengembalikan objek yang menjelaskan antarmuka jaringan di komputer lokal.
GetIPProperties()	Mengembalikan objek yang menjelaskan konfigurasi antarmuka jaringan ini.
GetIPStatistics()	Mendapatkan statistik IP untuk instans ini NetworkInterface .
GetIPv4Statistics()	Mendapatkan statistik IPv4 untuk instans ini NetworkInterface .
GetIsNetworkAvailable()	Menunjukkan apakah ada koneksi jaringan yang tersedia.
GetPhysicalAddress()	Mengembalikan Media Access Control (MAC) atau alamat fisik untuk adaptor ini.
