<div>Thank you so much for your answer. I think I should explain about my problem a little bit more. I want to listen a network which has an internet connection around 50mbit/sec. My problem is i have to use C# for this program and so i need to wrap winpcap
to use it. There are some open source C# wrappers like sharppcap and <a href="http://pcap.net/" target="_blank">
pcap.net</a>. I wonder if i use these wrappers can i listen and capture 50mbit/sec without packet loss. Is using a wrapper will reduce the performance of winpcap? I just need to listen, capture and save them to a dump file so my wrapper will not be much a big
project. Do writing my own little wrapper help me to reduce performance reduction?<br>
