获取访问用户的MAC信息

最近公司要获取登陆用的mac地址信息，找了很久最终还是没有找到；只找到了获得本机信息和同一域内mac地址信息。当使用代理服务器时，获取的是代理服务器信息，虽然失败了，但是网上找到一些信息还是有点用途的

1.用代码获取本机的相关信息，包括操作系统的登录用户名，PC类型，物理内存，计算机名称

添加Computer类，类代码如下：

using System;using System.Collections.Generic;using System.Web;using System.Management;/// <summary>///Computer 的摘要说明///获取本机的用户信息/// </summary>public class Computer{ public string CpuID; public string MacAddress; public string DiskID; public string IpAddress; public string LoginUserName; public string ComputerName; public string SystemType; public string TotalPhysicalMemory; //单位：M private static Computer _instance; public static Computer Instance() { if (_instance == null) _instance = new Computer(); return _instance; } public Computer() { CpuID = GetCpuID(); MacAddress = GetMacAddress(); DiskID = GetDiskID(); IpAddress = GetIPAddress(); LoginUserName = GetUserName(); SystemType = GetSystemType(); TotalPhysicalMemory = GetTotalPhysicalMemory(); ComputerName = GetComputerName(); } string GetCpuID() { try { //获取CPU序列号代码 string cpuInfo = "";//cpu序列号 ManagementClass mc = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { cpuInfo = mo.Properties["ProcessorId"].Value.ToString(); } moc = null; mc = null; return cpuInfo; } catch { return "unknow"; } finally { } } string GetMacAddress() { try { //获取网卡Mac地址 string mac = ""; ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { if ((bool)mo["IPEnabled"] == true) { mac = mo["MacAddress"].ToString(); break; } } moc = null; mc = null; return mac; } catch { return "unknow"; } finally { } } string GetIPAddress() { try { //获取IP地址 string st = ""; ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { if ((bool)mo["IPEnabled"] == true) { //st=mo["IpAddress"].ToString(); System.Array ar; ar = (System.Array)(mo.Properties["IpAddress"].Value); st = ar.GetValue(0).ToString(); break; } } moc = null; mc = null; return st; } catch { return "unknow"; } finally { } } string GetDiskID() { try { //获取硬盘ID String HDid = ""; ManagementClass mc = new ManagementClass("Win32_DiskDrive"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { HDid = (string)mo.Properties["Model"].Value; } moc = null; mc = null; return HDid; } catch { return "unknow"; } finally { } } /// <summary> /// 操作系统的登录用户名 /// </summary> /// <returns></returns> string GetUserName() { try { string st = ""; ManagementClass mc = new ManagementClass("Win32_ComputerSystem"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { st = mo["UserName"].ToString(); } moc = null; mc = null; return st; } catch { return "unknow"; } finally { } } /// <summary> /// PC类型 /// </summary> /// <returns></returns> string GetSystemType() { try { string st = ""; ManagementClass mc = new ManagementClass("Win32_ComputerSystem"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { st = mo["SystemType"].ToString(); } moc = null; mc = null; return st; } catch { return "unknow"; } finally { } } /// <summary> /// 物理内存 /// </summary> /// <returns></returns> string GetTotalPhysicalMemory() { try { string st = ""; ManagementClass mc = new ManagementClass("Win32_ComputerSystem"); ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { st = mo["TotalPhysicalMemory"].ToString(); } moc = null; mc = null; return st; } catch { return "unknow"; } finally { } } /// <summary> /// 计算机名称 /// </summary> /// <returns></returns> string GetComputerName() { try { return System.Environment.GetEnvironmentVariable("ComputerName"); } catch { return "unknow"; } finally { } }}

 

2.获取登陆用户的mac地址信息，可惜的是只能在局域网中，并且不能使用代理服务器，使用代理后获取的是代理服务器信息

#region 获取登陆用户的MAC地址信息 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！" + "<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)); } } } Response.Write("欢迎来自IP为" + userip + "<br>" + ",MAC地址为" + mac_dest + "的朋友！" + "<br>"); } catch (Exception err) { Response.Write(err.Message); } #endregion
