求助关于获取客户端mac地址！
Request.UserHostAddress.ToString().Trim();可以获取客户端IP地址，但是这个地址是会改变的！
怎么才能实现获取客户端的MAC地址，
要做到不管客户端是通过路由还是通过拨号上网都能取得！
谢谢!
可以用JS或vbscript来调用WMI接口来获取Client端的MAC地址.

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;

关于WMI的详细信息可以参看MSDN:

平心而论，WMI的很强大的。原先需要动用重量级编程工具才能做到的事，现在用js/vbscript就可以做了。
获取多块网卡的MAC地址:
if(objObject.MACAddress != null && objObject.MACAddress != "undefined"){
MACAddr = objObject.MACAddress;
alert( MACAddr );
}
缺点:需要ActiveX支持.对MS-WIN系统有效.
