如何获取客户端MAC地址？
我尝试了两种网上中最常见的获取MAC地址的方法，可是获取到的都是服务器的MAC地址;
小妹，在这里请假各位，希望可以有新的收获；
谢谢……

------解决方案--------------------
js 获取，返回服务器
------解决方案--------------------
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();

string str = "";
foreach (ManagementObject mo in moc)
{
if ((bool)mo["IPEnabled"] == true)
str = mo["MacAddress"].ToString();
}
return str;


------解决方案--------------------
安全性问题，activex控件

[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);

private string GetMac()
{
try
{
string userip = Request.UserHostAddress;
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP); //目的地的ip 
Int32 lhost = inet_addr(""); //本地服务器的ip 
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest, 0, ref macinfo, ref len);
string mac_src = macinfo.ToString("X");
if (mac_src == "0")
{
if (userip == "127.0.0.1")
Response.Write("正在访问Localhost!");
else
Response.Write("欢迎来自IP为" + userip + "的朋友！" + "");
return "";
}

while (mac_src.Length < 12)
{
mac_src = mac_src.Insert(0, "0");
}

string mac_dest = "";

for (int i = 0; i < 11; i++)
{
if (0 == (i % 2))
{
if (i == 10)
{
mac_dest = mac_dest.Insert(0, mac_src.Substring(i, 2));
}
else
{
mac_dest = "-" + mac_dest.Insert(0, mac_src.Substring(i, 2));
}
}
}
return mac_dest;



}
catch (Exception ex)
{

}
return "";

}

这个可以的，测过了
