Haven't worked with that framework, but according to description article... do you call captureFileReader.Write(e.Packet) later?

the prb is on the
CaptureFileWriterDevice captureFileReader = new CaptureFileWriterDevice(devices[i], "D:\\Documents and Settings\\amin\\Mes documents\\file.pcap");

Error 2 Argument '1 ': can not convert from' SharpPcap.ICaptureDevice 'to' SharpPcap.LibPcap.LibPcapLiveDevice '

According to this error, there may be mess with namespaces. You use SharpPcap.LibPcap.CaptureFileWriterDevice.CaptureFileWriterDevice and it rejects SharpPcap.ICaptureDevice object... is there SharpPcap.CaptureFileWriterDevice class in this framework?

no I don't have a SharpPcap.CaptureFileWriterDevice class in this framework

Ok, have you tried cast?
I mean:
SharpPcap.LibPcap.LibPcapLiveDevice pDevice = devices[i] as SharpPcap.LibPcap.LibPcapLiveDevice;
if (null != pDevice)
{
CaptureFileWriterDevice captureFileReader = new CaptureFileWriterDevice(pDevice, "D:\\Documents and Settings\\amin\\Mes documents\\file.pcap");
...
}

You should really read the FAQ before posting here: "it doesn't work" tell us near zero about your prblem.
I may just guess the above statement is throwing an exception, but you told us nothing about.
Please elaborate.
Moreover I suppose you have the source code of the framework you are using (available here[^]) hence you might delve inside it to find what is going wrong.
