获得远程计算机MAC地址代码
获取客户端IP及MAC地址，下边分为了C#后台获取的方法和前台Javascript(调用ActiveX)获取的方法
C#代码获取：
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Runtime.InteropServices;namespace MyTest{ public partial class mac : System.Web.UI.Page { [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); protected void Page_Load(object sender, EventArgs e) { GetMac(); } //获取客户端IP 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 private void GetMac() { // 在此处放置用户代码以初始化页面 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)); } } } Response.Write("欢迎来自IP为" + userip + "" + ",MAC地址为" + mac_dest + "的朋友！" + ""); } catch (Exception err) { Response.Write(err.Message); } } }} |
Javascript获取：
