void ShowNetworkInterfaces()

Keterangan

Alamat MAC, atau alamat fisik, adalah alamat perangkat keras yang secara unik mengidentifikasi setiap simpul, seperti komputer atau printer, di jaringan.

Instans kelas ini dikembalikan oleh NetworkInterface.GetPhysicalAddress metode .

Konstruktor

PhysicalAddress(Byte[])

Menginisialisasi instans baru kelas PhysicalAddress.

Bidang

None	Mengembalikan instans baru PhysicalAddress dengan alamat panjang nol. Bidang ini hanya-baca.

Metode

Equals(Object)	Membandingkan dua PhysicalAddress instans.
GetAddressBytes()	Mengembalikan alamat instans saat ini.
GetHashCode()	Mengembalikan nilai hash alamat fisik.
GetType()	Mendapatkan dari instans Type saat ini. (Diperoleh dari Object)
MemberwiseClone()	Membuat salinan dangkal dari saat ini Object. (Diperoleh dari Object)
Parse(ReadOnlySpan<Char>)	Mengurai rentang yang ditentukan dan menyimpan kontennya sebagai byte alamat dari yang PhysicalAddress dikembalikan oleh metode ini.
Parse(String)	Mengurai yang ditentukan String dan menyimpan kontennya sebagai byte alamat dari yang PhysicalAddress dikembalikan oleh metode ini.
ToString()	Mengembalikan representasi alamat instans String ini.
TryParse(ReadOnlySpan<Char>, PhysicalAddress)	Mencoba mengonversi representasi rentang alamat perangkat keras menjadi PhysicalAddress instans. Nilai yang dikembalikan menunjukkan apakah konversi berhasil.
TryParse(String, PhysicalAddress)	Mencoba mengonversi representasi string alamat perangkat keras menjadi PhysicalAddress instans. Nilai yang dikembalikan menunjukkan apakah konversi berhasil.
