asp.net get the network card address

废了废了

How to obtain the network card address in the client LAN in asp.net? Give me an idea!

Only the MAC of the service can be obtained, not the MAC of the client

I can now get the client's network card address, but not in the LAN

I can now get the client's network card address, but not in the LAN? ? ? ?
Isn't it? It should be possible to get a local area network, but not a public network

I also have one:
It is impossible to come through the web page, but you can use ActiveX, you save the following code as an html, and then open it to see the effect



<HTML><HEAD><TITLE>Get client MAC and username</TITLE>
<META http-equiv=Content-Type content="text/html; charset=gb2312">
<SCRIPT language=JScript event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for=foo>
document.forms[0].txtMACAddr.value=unescape(MACAddr);
document.forms[0].txtIPAddr.value=unescape(IPAddr);
document.forms[0].txtDNSName.value=unescape(sDNSName);
//document.formbar.submit();
  </SCRIPT>

<SCRIPT language=JScript event=OnObjectReady(objObject,objAsyncContext) for=foo>
   if(objObject.IPEnabled != null&&objObject.IPEnabled != "undefined"&&objObject.IPEnabled == true)
   {
    if(objObject.MACAddress != null&&objObject.MACAddress != "undefined")
    MACAddr = objObject.MACAddress;
    if(objObject.IPEnabled&&objObject.IPAddress(0) != null&&objObject.IPAddress(0) != "undefined")
    IPAddr = objObject.IPAddress(0);
    if(objObject.DNSHostName != null&&objObject.DNSHostName != "undefined")
    sDNSName = objObject.DNSHostName;
    }
  </SCRIPT>

<META content="MSHTML 6.00.2800.1106" name=GENERATOR></HEAD>
<BODY>
<OBJECT id=locator classid=CLSID:76A64158-CB41-11D1-8B02-00600806D9B6 VIEWASTEXT></OBJECT>
<OBJECT id=foo classid=CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223></OBJECT>
<SCRIPT language=JScript>
   var service = locator.ConnectServer();
   var MACAddr;
   var IPAddr;
   var DomainAddr;
   var sDNSName;
   service.Security_.ImpersonationLevel=3;
   service.InstancesOfAsync(foo,'Win32_NetworkAdapterConfiguration');
   </SCRIPT>

<FORM id="formfoo" name="formbar" action="index.do" method="post"><INPUT value="00-11-11-B4-52-EF" name="txtMACAddr"> <INPUT value="210.42.38.50" name="txtIPAddr"> <INPUT value="zhupan" name="txtDNSName"> </FORM></BODY></HTML>
