足迹—— 获取客户端MAC地址
为了CRM系统的安全性，今天领导要求员工登录时候都要验证他们电脑的信息，匹配之后才允许登录。我左思右想还是验证网卡的MAC吧。首先在Commond层加个获取网卡信息的类GetNetCardMAC
using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
namespace JL.CRM.Common
{
public class GetNetCardMAC
{
private ManagementClass mc;
private ManagementObjectCollection moc;
public GetNetCardMAC()
{ }
/// <summary>
/// 取得设备网卡的MAC地址
/// </summary>
public string GetNetCardMacAddress()
{
mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
moc = mc.GetInstances();
string str = "";
foreach (ManagementObject mo in moc)
{
if ((bool)mo["IPEnabled"] == true)
str = mo["MacAddress"].ToString();
}
return str;
}
}
}
切记要引用命名空间：using System.Management。
心中窃喜，呵呵还是比较简单的。测试，晕 ！ 这么做获取的是服务器的MAC。
要获取客户端的MAC用C#做就比较复杂了。网上也有很多类似的例子，不过获取客户端的信息最好还是用客户端脚本比较好。下面是个JavaScript的获取MAC的例子（转）：
<HTML><HEAD><TITLE>WMI Scripting HTML</TITLE>
<META http-equiv=Content-Type content="text/html; charset=gb2312">
<SCRIPT language=JScript event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for=foo>
document.forms[0].txtMACAddr.value=unescape(MACAddr);
document.forms[0].txtIPAddr.value=unescape(IPAddr);
document.forms[0].txtDNSName.value=unescape(sDNSName);
//document.formbar.submit();
</SCRIPT>
<SCRIPT language=JScript event=OnObjectReady(objObject,objAsyncContext) for=foo>
if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
{
if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
MACAddr = objObject.MACAddress;
if(objObject.IPEnabled && objObject.IPAddress(0) != null && objObject.IPAddress(0) != "undefined")
IPAddr = objObject.IPAddress(0);
if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
sDNSName = objObject.DNSHostName;
}
</SCRIPT>
<META content="MSHTML 6.00.2800.1106" name=GENERATOR></HEAD>
<BODY>

<SCRIPT language=JScript>
var service = locator.ConnectServer();
var MACAddr ;
var IPAddr ;
var DomainAddr;
var sDNSName;
service.Security_.ImpersonationLevel=3;
service.InstancesOfAsync(foo, 'Win32_NetworkAdapterConfiguration');
</SCRIPT>
<FORM id=formfoo name=formbar action=NICPost.asp method=post><INPUT value=00:05:5D:0E:C7:FA name=txtMACAddr> <INPUT value=192.168.0.2 name=txtIPAddr> <INPUT value=typ name=txtDNSName> </FORM></BODY></HTML>
经测试 ok 没有问题 o(∩_∩)o...哈哈 继续做……
