用vs2012编写c程序，如何获得CPU ID、MAC地址和硬盘序列号

MAC（Media Access Control或者Medium Access Control）地址，意译为媒体访问控制，或称为物理地址、硬件地址，用来定义网络设备的位置。在OSI模型中，第三层网络层负责 IP地址，第二层数据链路层则负责 MAC地址。因此一个主机会有一个MAC地址，而每个网络位置会有一个专属于它的IP地址。

一般网站是不能获取到电脑的MAC地址。

如果是C/S结构，在局域网中还可以取得客户端得mac地址，通过广域网是不能得到地。

如果是B/S，在哪里也得不到客户端得mac地址的。

本程序属于一种特别的方法 使用范围比较有限 而且有一定的危险性 借鉴了asp后门里的一些方法 下面是程序代码 ＜%dim remoteaddrif Request ServerVariables( >

按快捷键WIN+R调出运行工具。然后再输入CMD,再回车或点击确定

输入ipconfig -all命令按回车，就可以看得到这台电脑上的有线和无线网卡的MAC地址。

很简单取得对方IP后,将其传入下面函数GetMACAddress即可得到string类型的MAC地址:
