Error: 'PacketCapture' does not contain a definition for 'Packet'

[lev99999]

Hello,

I use .net core 7 and I downloaded sharpPcap library to vscode using the command:
dotnet add package SharpPcap --version 6.2.5

The library was successfully installed, but when I try to use this command for example:
using var device = new CaptureFileReaderDevice("filename.pcap");
device.Open();
device.OnPacketArrival += Device_OnPacketArrival;
device.Capture();
(of course I added this: using SharpPcap).

I got this error:
'PacketCapture' does not contain a definition for 'Packet' and no accessible extension method 'Packet' accepting a first argument of type 'PacketCapture' could be found

Thank You

@lev99999 full code snippet please and full stack trace/line numbers

[lev99999]

This is the code:

using Microsoft.AspNetCore.Mvc;

using SharpPcap;



namespace MyProjectApi.Controllers;



[ApiController]

[Route("[controller]")]

public class PcapsController : ControllerBase

{

    public void Device_OnPacketArrival(object s, PacketCapture e)

    {

        Console.WriteLine(e.Packet);

    }



    [HttpGet(Name = "readPcaps")]

    public void readPcaps()

    {

        using var device = new CaptureFileReaderDevice("log111622.pcap");

        device.Open();

        device.OnPacketArrival += Device_OnPacketArrival;

        device.Capture();

    }

}

And this is the results of building:

Change e.Packet to e.GetPacket().GetPacket()
