Amany,
Download yourself a copy of Ethereal. It's free.

Hi amany,

The MAC address appears in the Ethernet header, and you cannot easily read
that. However, if you have an instance of a Socket object, and are
receiving the packet through the Socket, then you can adjust the parameters
of the Socket's IP layer to include the IP header.

You need to take a look at the SetSocketOption method of the Socket class,
and you need to set the option HeaderIncluded on the IP layer. MSDN has an
example about using SetSocketOption, on their website. Here is the URL:

A quick Google, with the right keywords, turns up some relevant examples.
Remember: If you turn on HeaderIncluded, you also have to format your own
IP header.
