Question

在.net的web服务器中可以不安装插件得到访问者的机器mac地址吗？

Answer 1

#region 获得客户端mac地址
    public string GetCustomerMac(string IP) //para IP is the client's IP
    {
        if (IP == "127.0.0.1")
        {
            return GetLocalMac();
        }//"00-04-61-5C-31-52";//00-0F-1F-C6-B2-B3 
        else
        {
            string dirResults = "";
            ProcessStartInfo psi = new ProcessStartInfo();
            Process proc = new Process();
            psi.FileName = "nbtstat";
            psi.RedirectStandardInput = false;
            psi.RedirectStandardOutput = true;
            psi.Arguments = "-A " + IP;
            psi.UseShellExecute = false;
            proc = Process.Start(psi);
            dirResults = proc.StandardOutput.ReadToEnd();
            proc.WaitForExit();
            dirResults = dirResults.Replace("\r", "").Replace("\n", "").Replace("\t", "");
            int i = dirResults.LastIndexOf("=");
            dirResults = dirResults.Substring(i + 2, 17);
            if (dirResults.IndexOf("本地连接") != -1)
            { dirResults = "没有得到mac"; }
            return dirResults;
        }
    }
     #endregion

这个古籍得需要客户端的权限的 如果有客户端防火墙等估计获取不到的

你好！
     找到一个使用JS来获取MAC的实例，希望对你有帮助：

document.forms[ 0 ].txtMACAddr.value = unescape(MACAddr);
document.forms[ 0 ].txtIPAddr.value = unescape(IPAddr);
document.forms[ 0 ].txtDNSName.value = unescape(sDNSName);
// document.formbar.submit();

局域网内可以，过了交换机路由就不行了
