构造函数

VpnPacketBuffer(VpnPacketBuffer, UInt32, UInt32)

未使用。

属性

AppId

获取表示导致此数据包流动的应用的应用 ID。 这仅在流的第一个数据包上存在。 此属性的存在指示它是第一个数据包。
Buffer

获取内存缓冲区对象，该对象旨在包含要作为 IVpnPacketBufferList 的一部分发送或接收的日期数据包。
Status

获取 VpnPacketBuffer 的状态。 status 属性可用于在操作 IVpnPacketBufferList 时报告错误。
TransportAffinity

获取或设置一个数字，指定使用哪个传输对象，如 VpnChannel：Start* 方法中指定的。 这允许在main和可选传输之间进行选择。
TransportContext

获取或设置传输上下文对象，例如主机或服务器的名称。
