ASP.NET获取客户端IP及MAC地址
[解决办法]
关注，不知道除了activx控件，其他方法能不能获取广域网的mac，理论不可行~~
[解决办法]
获取客户端IP：Request.UserHostAddress
如要获取客户端本机的MAC地址就相对复杂些，得导入调用两个API，用ARP协议获取，但这样只能获取到同网段机器的MAC，对于跨网段的得利用IP扫描或cmd中nbtstat命令获取MAC地址。也可通过读取系统注册表值或WMI的数据库来获取。
[解决办法]
private string GetClientIP()
{
string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}
if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.UserHostAddress;
}
return result;
}
获取MAC地址:
[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 void Page_Load(object sender, System.EventArgs e)
{
try
{
string userip=Request.UserHostAddress;
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP);
Int32 lhost = inet_addr("");
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 ("");
else
Response.Write ("" + userip + "" + "<br>");
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));
}
}
}
}
catch(Exception err)
{
Response.Write(err.Message);
}
}

你发的那个例子有没有自己实验过，我估计是C/S结构改的。在B/S上能用吗？？非常怀疑！
[解决办法]
B/S下是不可能的.(获得的IP也是代理之后的,所以拿到的IP不是100%真实. MAC地址在广域网下就别想了,除非你要求client装你自己的ocx)

[解决办法]
- C# code
string userip=Request.UserHostAddress; string strClientIP = Request.UserHostAddress.ToString().Trim();
[解决办法]
- C# code
哦，是这句string ip = Request.ServerVariables["REMOTE_ADDR"];
[解决办法]
[解决办法]
个人认为C#不可能在广域网上获取客户端MAC地址。除非用JS或客户端插件。
