NetworkInterface.GetPhysicalAddress 메서드

정의

네임스페이스:

System.Net.NetworkInformation

어셈블리:

System.Net.NetworkInformation.dll

Source:

NetworkInterface.cs

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

public:
 virtual System::Net::NetworkInformation::PhysicalAddress ^ GetPhysicalAddress();

public virtual System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();

abstract member GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
override this.GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress

Public Overridable Function GetPhysicalAddress () As PhysicalAddress

반환

PhysicalAddress

실제 주소가 들어 있는 PhysicalAddress 개체입니다.

예제

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