读取客户端mac地址判断访问权限

一、用wmi读取本机的mac地址的ActiveX

using System;
using System.Runtime.InteropServices;
using System.Management;
namespace NGetid
{
  public interface Nst
  {
      string FGet();
      string GetHardDiskID();
  }
  [ClassInterface(ClassInterfaceType.AutoDual)]
  public class NGetClass : Nst
  {
      public string FGet()
      {
          return "Success";
      }
      public String GetHardDiskID()
      {
          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().Replace(":", "");
              mo.Dispose();
          }
          return mac;
      }
  }
}

编译为dll: csc /t:library ngetclass.cs
在客户机安装： regasm ngetclass /tlb /codebase
二、服务器端接收mac地址,用ajaxpro进行验证返回验证结果
前台：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="getmac.aspx.cs" Inherits="getmac" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>读取Mac地址进行身份验证</title>
</head>
<body>
    <form id="form1" runat="server">
        <div id="top">
        您的网卡Mac地址为：
        <asp:TextBox ID="txtMacAddress" runat="server" Width="100px"></asp:TextBox>
        <asp:Label ID="lbAlert" runat="server" Width="100px">aaa</asp:Label>
        </div>
        <div id="login"  style="visibility:hidden">
            <asp:Button ID="Button1" runat="server" Text="登陆" />
        </div>
        <script type="text/javascript">
            var macAddress=document.getElementById("txtMacAddress");
            var x=new ActiveXObject("NGetid.NGetClass");
            var value=x.GetHardDiskID();
            macAddress.value=value;
            var v=getmac.checkmac(value).value;
                           var logindiv=document.getElementById("login");
            if(v=="ok")
            {
                logindiv.style.visibility = "visible";
                document.getElementById("lbAlert").innerText="验证通过";
            }
            else
            {
                logindiv.style.visibility = "hidden";
                document.getElementById("lbAlert").innerText="验证未通过";
            }
        </script>
    </form>
</body>
</html>

后台：

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class getmac : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        AjaxPro.Utility.RegisterTypeForAjax(typeof(getmac), this.Page);
    }
    [AjaxPro.AjaxMethod]
    public string  checkmac(string mac)
    {
        if (mac == "00E04CD67945")
        {
            return "ok";
        }
        else
        {
            return "error";
        }
    }
}

三、客户机需要把服务器的地址加入浏览器信任站点
由于没有数字签名，所以必须确认internet选项中允许未签名的activex，要不每次运行会出现确认窗口

四、运行效果
验证通过

验证未通过

也不知道有没有什么实用价值，o(∩_∩)o...。
