Get computer Mac Address using ASP.NET

Note that it depends on whether you need the MAC address for the client or the server. I assume you need it for the client, which is essentially not possible using ASP since ASP only executes in the server. So you need to do something that executes in the client, such as Kumar shows. So look for other articles and samples that use JavaScript and that work in all browsers or at least the ones you need to support. I don't know any specific but it should be relatively easy to find articles.
