从 c# 中的特定端口获取流数据

我正在尝试从特定端口获取流数据，数据来自应用程序，我想捕获它们。实际上，我捕获了数据，但我想它是编码的。

所以我尝试使用UTF-8，默认，ASCII等进行编码。

是否可以使用SharpPcap以可读格式查看数据？

这是我的示例代码：

        var time = e.Packet.Timeval.Date;
        var len = e.Packet.Data.Length;
        var packet = Packet.ParsePacket(e.Packet.LinkLayerType, e.Packet.Data);
        var tcpPacket = PacketDotNet.TcpPacket.GetEncapsulated(packet);
        if (tcpPacket != null)
        {
            var ipPacket = (IpPacket)tcpPacket.ParentPacket;
            IPAddress srcIp = ipPacket.SourceAddress;
            IPAddress dstIp = ipPacket.DestinationAddress;
            int srcPort = tcpPacket.SourcePort;
            int dstPort = tcpPacket.DestinationPort;
            if (dstPort == 31749)
            {
             string[] encs = new string[] {
