PhysicalAddress Constructor

Initializes a new instance of the PhysicalAddress class.

Namespace:  System.Net.NetworkInformation
Assembly:  System (in System.dll)

public PhysicalAddress(
	byte[] address


Type: System.Byte[]

A Byte array containing the address.

In common scenarios, applications do not need to call this constructor; instances of this class are returned by the GetPhysicalAddress method.

Note that you can also use the Parse method to create a new instance of PhysicalAddress.

The following code example creates a new PhysicalAddress object.

    public static PhysicalAddress[] StoreNetworkInterfaceAddresses()
    IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    if (nics == null || nics.Length < 1)
        Console.WriteLine("  No network interfaces found.");
        return null;

    PhysicalAddress[] addresses = new PhysicalAddress[nics.Length];
    int i = 0;
    foreach (NetworkInterface adapter in nics)
        IPInterfaceProperties properties = adapter.GetIPProperties();
        PhysicalAddress address = adapter.GetPhysicalAddress();
        byte[] bytes = address.GetAddressBytes();
        PhysicalAddress newAddress =  new PhysicalAddress(bytes);
    return addresses;
PhysicalAddress* StoreNetworkInterfaceAddresses() []
    IPGlobalProperties* computerProperties = IPGlobalProperties::GetIPGlobalProperties();
    NetworkInterface* nics[] = NetworkInterface::GetAllNetworkInterfaces();
    if (nics == 0 || nics->Length < 1)
        Console::WriteLine(S"  No network interfaces found.");
        return 0;

    PhysicalAddress* addresses[] = new PhysicalAddress*[nics->Length];
    int i = 0;
    IEnumerator* myEnum2 = nics->GetEnumerator();
    while (myEnum2->MoveNext())
        NetworkInterface* adapter = __try_cast<NetworkInterface*>(myEnum2->Current);
        IPInterfaceProperties* properties = adapter->GetIPInterfaceProperties();
        PhysicalAddress* address = adapter->GetPhysicalAddress();
        Byte bytes[] = address->GetAddressBytes();
        PhysicalAddress* newAddress =  new PhysicalAddress(bytes);
    return addresses;
