使用SharpPcap拦截和编辑数据包

Question

我看上去并且看不到任何关于此的信息。

所以我有一台电脑连接我的主电脑，我如何从我的主电脑拦截和编辑一个数据包（我知道是我的其他电脑）？我知道如何拦截它，但我在编辑它时找不到任何东西。

我目前的代码是：

static void Main()
{
    // Retrieve all capture devices
    var devices = CaptureDeviceList.New();

    var device = devices.FirstOrDefault(dev => dev.Description.ToLowerInvariant().Contains("intel(r)"));

    // check device isn't null
    if (device == null)
        throw new NullReferenceException();


    while(true)
    {
        // open device
        device.Open();

        var capture = device.GetNextPacket();
        if (capture == null || capture.Data == null)
            continue;

        var packet = PacketDotNet.Packet.ParsePacket(capture.LinkLayerType, capture.Data);
        var asciiz = Encoding.ASCII.GetString(capture.Data);


        if (asciiz.ToLowerInvariant().Contains("xeraxic"))
        {
            asciiz = asciiz.Replace("<view>1</view>",
                                    "<view>2</view>");

            packet.PayloadPacket.PayloadPacket.PayloadData = Encoding.ASCII.GetBytes(asciiz);
            Console.WriteLine("Modified Packet, fingers crossed");
        }

        // close device
        device.Close();
    }
}
