PhysicalAddress Class
Provides the Media Access Control (MAC) address for a network interface (adapter).
Assembly: System (in System.dll)
The MAC address, or physical address, is a hardware address that uniquely identifies each node, such as a computer or printer, on a network.
Instances of this class are returned by the NetworkInterface.GetPhysicalAddress method.
The following code example displays the physical addresses of all interfaces on the local computer.
void ShowNetworkInterfaces()
{
IPGlobalProperties* computerProperties = IPGlobalProperties::GetIPGlobalProperties();
NetworkInterface* nics[] = NetworkInterface::GetAllNetworkInterfaces();
Console::WriteLine(S"Interface information for {0}.{1} ",
computerProperties->HostName, computerProperties->DomainName);
if (nics == 0 || nics->Length < 1)
{
Console::WriteLine(S" No network interfaces found.");
return;
}
Console::WriteLine(S" Number of interfaces .................... : {0}", (nics->Length).ToString());
IEnumerator* myEnum1 = nics->GetEnumerator();
while (myEnum1->MoveNext())
{
NetworkInterface* adapter = __try_cast<NetworkInterface*>(myEnum1->Current);
IPInterfaceProperties* properties = adapter->GetIPInterfaceProperties();
Console::WriteLine();
Console::WriteLine(adapter->Description);
Console::WriteLine(String::Empty->PadLeft(adapter->Description->Length,'='));
Console::WriteLine(S" Interface type .......................... : {0}", __box(adapter->Type));
Console::Write(S" Physical address ........................ : ");
PhysicalAddress* address = adapter->GetPhysicalAddress();
Byte bytes[] = address->GetAddressBytes();
for(int i = 0; i< bytes->Length; i++)
{
// Display the physical address in hexadecimal.
Console::Write(S"{0}", bytes[i].ToString(S"X2"));
// Insert a hyphen after each byte, unless we are at the end of the
// address.
if (i != bytes->Length -1)
{
Console::Write(S"-");
}
}
Console::WriteLine();
}
}
