asp.net 可以读出浏览者的 .MAC 地址吗？有其它方式可以读到唯一电脑吗？

如果读IP的话，客户端用ADSL重启后，IP就换了一个局域网内的用户怎么办呀！先谢谢了！

使用下类可以得到mac地址public class Win32 {
       [DllImport("Iphlpapi.dll")]
       public static  extern int SendARP(Int32 dest,Int32 host,ref IntPtr mac,ref IntPtr length);
       [DllImport("Ws2_32.dll")]
       public static extern Int32 inet_addr(string ip);
    }//调用dll的类     void mac()
      {
        Int32 ldest= Win32.inet_addr(Request.UserHostAddress);//目的地的ip
       Int32 lhost=Win32.inet_addr("190.10.51.5");//本地的ip
       try
        {
         Byte[] macinfo=new Byte[6];
         Int32 length=6;

         IntPtr mac=new IntPtr(macinfo[0]);
         IntPtr len=new IntPtr(6);
         int ii=Win32.SendARP(ldest,lhost, ref mac, ref len);


         ip+="**mac地址："+mac.ToString();
            }
         catch(Exception err)
          {
         ip+="";
          }
         }//mac
string strClientIP=this.Page.Request.UserHostAddress;
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "nbtstat.exe";
psi.RedirectStandardInput = false;
psi.RedirectStandardOutput = true;
psi.Arguments = "-A " + strClientIP;
psi.UseShellExecute = false;
Process ps = Process.Start(psi);
string strEnd = ps.StandardOutput.ReadToEnd();
ps.WaitForExit();
string[] strs = strEnd.Split('\n');
foreach(string s in strs)
{
if(s.Trim().ToLower().IndexOf("mac address") != -1)
{
string strTemp = s.Substring(s.IndexOf("Address =") + 10);
Response.Write(strTemp);
}
}
Response.End();
using System;
using System.Collections;
using System.Management;namespace ArLi.CommonPrj
{
public class GetOfMACAddr
{
public GetOfMACAddr()
{
} /// <summary>得到网卡 MAC 地址</summary>
/// <returns>返回地址数组，字符类型</returns>
/* 例： ArrayList myAddr = ArLi.CommonPrj.GetOfMACAddr.GetIt();
for (int i=0; i<myAddr.Count; i++) MessageBox.Show(myAddr[i].ToString());

*/
public static ArrayList GetIt() {
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
ArrayList strArr = new ArrayList();

//网卡数
foreach(ManagementObject mo in moc) {
if((bool)mo["IPEnabled"]) {
strArr.Add(mo["MacAddress"].ToString().Replace(":",""));
}
mo.Dispose();
} return strArr;
}
}
}
不应该用IntPtr的。通过它只能访问到Int32（在32位平台上）大小的内容。
下面修改过的C#代码已验证通过（未将网络字节顺序转换为主机字节顺序）： [DllImport("Iphlpapi.dll")]
private static extern int SendARP(Int32 dest,Int32 host,ref Int64 mac,ref Int32 length);
[DllImport("Ws2_32.dll")]
private static extern Int32 inet_addr(string ip); static private Int64 getRemoteMAC(string localIP, string remoteIP)
{
Int32 ldest= inet_addr(remoteIP); //目的地的ip
Int32 lhost= inet_addr(localIP); //本地服务器的ip try
{
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest,0, ref macinfo, ref len);
return macinfo;
}
catch(Exception err)
{
Console.WriteLine("Error:{0}",err.Message);
}
return 0;
} 至于第二个问题，在标准网络协议下，ARP包是不可能跨网段传输的，故想通
过ARP协议是无法查询跨网段设备MAC地址的。
从服务端可以取得相同网段的网卡的MAC地址,但对于不同网段的就无能为力.不过,用客户端脚本也是可以获取的,示例如下:
