IPInterfaceProperties.MulticastAddresses 속성

정의

네임스페이스:

System.Net.NetworkInformation

어셈블리:

System.Net.NetworkInformation.dll

이 인터페이스에 할당된 멀티캐스트 주소를 가져옵니다.

public:
 abstract property System::Net::NetworkInformation::MulticastIPAddressInformationCollection ^ MulticastAddresses { System::Net::NetworkInformation::MulticastIPAddressInformationCollection ^ get(); };

public abstract System.Net.NetworkInformation.MulticastIPAddressInformationCollection MulticastAddresses { get; }

member this.MulticastAddresses : System.Net.NetworkInformation.MulticastIPAddressInformationCollection

Public MustOverride ReadOnly Property MulticastAddresses As MulticastIPAddressInformationCollection

속성 값

MulticastIPAddressInformationCollection

이 인터페이스에 대한 멀티캐스트 주소가 들어 있는 MulticastIPAddressInformationCollection입니다.

예제

다음 코드 예제에서는 로컬 컴퓨터의 네트워크 인터페이스에 대 한 멀티 캐스트 주소를 표시 합니다.

설명

멀티캐스트 주소는 여러 컴퓨터를 식별합니다. 멀티캐스트 주소로 전송된 패킷은 주소로 식별된 모든 컴퓨터로 전송됩니다.
