屬性

AppId

取得應用程式標識碼，表示造成此封包流動的應用程式。 這隻會出現在流程的第一個封包上。 這個屬性的存在表示它是第一個封包。
Buffer

取得記憶體緩衝區物件，其設計目的是要包含在 IVpnPacketBufferListIVpnPacketBufferList 中要傳送或接收的封包。
Status

取得 VpnPacketBuffer的狀態。 操作 IVpnPacketBufferList 時，狀態屬性可用來報告錯誤。
TransportAffinity

取得或設定數位，指定 VpnChannel：Start* 方法中所指定要使用的傳輸物件。 這允許在main和選擇性傳輸之間進行選取。
TransportContext

取得或設定傳輸內容物件，例如主機或伺服器的名稱。
