NetworkInterface.GetPhysicalAddress 메서드

정의

이 어댑터에 대한 MAC(Media Access Control) 또는 실제 주소를 반환합니다.

public:
 virtual System::Net::NetworkInformation::PhysicalAddress ^ GetPhysicalAddress();
public:
 abstract System::Net::NetworkInformation::PhysicalAddress ^ GetPhysicalAddress();
public virtual System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();
public abstract System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();
abstract member GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
override this.GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
abstract member GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
Public Overridable Function GetPhysicalAddress () As PhysicalAddress
Public MustOverride Function GetPhysicalAddress () As PhysicalAddress

반환

실제 주소가 들어 있는 PhysicalAddress 개체입니다.

예제

다음 코드 예제에서는 로컬 컴퓨터에 있는 모든 인터페이스의 실제 주소를 표시 합니다.
