PhysicalAddress Class
Visual Studio 2010
Provides the Media Access Control (MAC) address for a network interface (adapter).
Assembly: System (in System.dll)
The PhysicalAddress type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Equals | Compares two PhysicalAddress instances. (Overrides Object::Equals(Object).) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetAddressBytes | Returns the address of the current instance. |
![]() | GetHashCode | Returns the hash value of a physical address. (Overrides Object::GetHashCode().) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | Parse | Parses the specified String and stores its contents as the address bytes of the PhysicalAddress returned by this method. |
![]() | ToString | Returns the String representation of the address of this instance. (Overrides Object::ToString().) |
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(); array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces(); Console::WriteLine( L"Interface information for {0}.{1} ", computerProperties->HostName, computerProperties->DomainName ); if ( nics == nullptr || nics->Length < 1 ) { Console::WriteLine( L" No network interfaces found." ); return; } Console::WriteLine( L" Number of interfaces .................... : {0}", (nics->Length).ToString() ); IEnumerator^ myEnum1 = nics->GetEnumerator(); while ( myEnum1->MoveNext() ) { NetworkInterface^ adapter = safe_cast<NetworkInterface^>(myEnum1->Current); IPInterfaceProperties^ properties = adapter->GetIPProperties(); Console::WriteLine(); Console::WriteLine( adapter->Description ); Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) ); Console::WriteLine( L" Interface type .......................... : {0}", adapter->NetworkInterfaceType ); Console::Write( L" Physical address ........................ : " ); PhysicalAddress^ address = adapter->GetPhysicalAddress(); array<Byte>^bytes = address->GetAddressBytes(); for ( int i = 0; i < bytes->Length; i++ ) { // Display the physical address in hexadecimal. Console::Write( L"{0}", bytes[ i ].ToString( L"X2" ) ); // Insert a hyphen after each byte, unless we are at the end of the // address. if ( i != bytes->Length - 1 ) { Console::Write( L"-" ); } } Console::WriteLine(); } }
