缺少CaptureEventArgs.Packet的提取方法

Question

所以，我试图使用Sharppcap来嗅探数据包，并密切关注codeproject上开发人员的Sharppcap教程，我尝试在extract()上调用CaptureEventArgs.Packet方法。似乎，extract()方法没有实现。码：

using PacketDotNet;
using SharpPcap;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;

namespace SnifferGUI
{
    class ProjectBehaviour
    {
        public void Initsniff()
        {
            CaptureDeviceList captureDeviceList = CaptureDeviceList.Instance;

            if(captureDeviceList.Count < 1)
            {
                throw new InsufficientExecutionStackException();
            }
            ICaptureDevice device = captureDeviceList[1]; //todo
            device.OnPacketArrival += new SharpPcap.PacketArrivalEventHandler(device_OnPacketArrival);

            device.Open(DeviceMode.Promiscuous, 0);

            device.StartCapture();
        }

        private void device_OnPacketArrival(object sender, CaptureEventArgs e)
        {
            var tcp = (TcpPacket)e.Packet.Extract(typeof(TcpPacket)); //According to the tutorial, this is a valid expression.
        }
    }

}

我的目标是将收到的数据包解析为TcpPacket以进一步推进。我想存储和显示源/目标IP和端口，时间戳等。那么，我错过了什么吗？

所以，是的...在联系了开发者via issue on the official github repository之后，我们得出的结论是教程已经过时了。这里提供了最新的示例：click!
