有一个网站挂在一个托管服务器上，我们这边每台机器浏览，如何获取自己的MAC地址？
/// <summary>
/// 获取客户端Mac地址
/// </summary>
public class GetMacAddress
{
[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);
// <summary>
/// 取得客户端MAC地址
/// </summary>
public string GetNetCardMacAddress()
{
string userip = HttpContext.Current.Request.UserHostAddress;
string strClientIP = HttpContext.Current.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");
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;
}
}
这个在局域网能获取到 放在外网就不能获取
