Asp.net中获取IP 和 MAC

获取IP

1、ASP.NET中获取

获取服务器的IP地址：
using System.Net;

string myIP,myMac;
System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
if ( addressList.Length>1)
{
      myIP = addressList[0].ToString();
      myMac = addressList[1].ToString();
}
else
{
      myIP = addressList[0].ToString();
      myMac = "没有可用的连接"；
}
myIP地址就是服务器端的ip地址。

获取客户端的ip地址，可以使用

//获取登录者ip地址
string ip = Request.ServerVariables["REMOTE_ADDR"].ToString();

2、通过JS获取
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
</head>

<body>

<object classid="CLSID:76A64158-CB41-11D1-8B02-00600806D9B6" id="locator" style="display:none;visibility:hidden"></object>
<object classid="CLSID:75718C9A-F029-11d1-A1AC-00C04FB6C223" id="foo" style="display:none;visibility:hidden"></object>

<form name="myForm">
<br/>MAC地址：<input type="text" name="macAddress">
<br/>IP地址：<input type="text" name="ipAddress">
<br/>主机名：<input type="text" name="hostName">
</form>

</body>
</html>
<script language="javascript">
var sMacAddr="";
var sIPAddr="";
var sDNSName="";

var service = locator.ConnectServer();
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');

</script>

<script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JavaScript">
        if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true){
                          if(objObject.IPEnabled && objObject.IPAddress(0) !=null && objObject.IPAddress(0) != "undefined")
                                        sIPAddr = objObject.IPAddress(0);
                          if(objObject.MACAddress != null &&objObject.MACAddress != "undefined")
                                        sMacAddr = objObject.MACAddress;
                          if(objObject.DNSHostName != null &&objObject.DNSHostName != "undefined")
                                        sDNSName = objObject.DNSHostName;
         }
</script>

<script FOR="foo" EVENT="OnCompleted(hResult,pErrorObject, pAsyncContext)" LANGUAGE="JavaScript">
       myForm.macAddress.value=sMacAddr;
       myForm.ipAddress.value=sIPAddr;
       myForm.hostName.value=sDNSName;
</script>
