アセンブリ: System (system.dll 内)

Dim instance As IPInterfaceProperties Dim value As UnicastIPAddressInformationCollection value = instance.UnicastAddresses
public: virtual property UnicastIPAddressInformationCollection^ UnicastAddresses { UnicastIPAddressInformationCollection^ get () abstract; }
このインターフェイスのユニキャスト アドレスを格納している UnicastIPAddressInformationCollection。
