VC中可以用什么方法取到本机的网卡物理地址

在网上找了1天了，那些NCB、GetAdaptersInfo都不对的~
自己电脑的系统MAC一改就变了~；
希望大家能帮我解决~谢谢了。

顶起~别沉了

#2

网卡物理地址是指MAC地址吗？GetAdaptersInfo具体怎么不对？

#3

他的意思是RING3的API获取的不一定是网卡原始的MAC地址。
因为可以在网卡属性里更改网卡的MAC。

#4

GetAdaptersInfo 就可以获取到MAC地址，一般MAC是网卡物理地址，一般情况都不会改变，除非你用工具等..
可以用ipconifg命令查看

我是在网络中修改它的系统mac的，一修改就变了，物理地址不是说不能改变的么？
所以我就觉得GetAdaptersInfo这个读取的应该是系统的mac而不是网卡的物理mac

VisualEleven的方法我没试过，我试试先，谢谢大家的帮忙~万分感谢！
