If you need an alternative for SharpPcap, you can use Pcap.Net.

All you need to do is build an EthernetLayer, ArpLayer and use the PacketBuilder to build a packet and send it.

It's simple, straight forward and easy to do.

There is an example of sending an arp packet in the source code download of sharppcap in the Examples directory off of the sourceforge project page, http://sourceforge.net/projects/sharppcap/

There were some issues with ARP in older versions but these have been resolved in the 4.0.0 release that came out 2011-09-13.

  • Drop me an email at chmorgan@gmail.com if you are having any trouble with getting the example to work. I can send you a pre-release directly if you'd like since I need to check on a few things before releasing the new version. – Chris Morgan Sep 12 '11 at 13:58
  • Is your mentioned example Example2.ArpResolve in http://sharppcap.git.sourceforge.net/git/gitweb.cgi?p=sharppcap/sharppcap;a=tree;f=Examples;hb=HEAD ? – Yasin Ozel Sep 12 '11 at 22:35
  • Yes. 4.0.0 is out now so if you grab the src release of that you can check out the examples without having to browse via the gitweb interface. – Chris Morgan Sep 14 '11 at 01:09
