VC 获取物理网卡的MAC地址
获取网卡的MAC地址的方法很多,如:Netbios,SNMP,GetAdaptersInfo等。经过测试发现 Netbios 方法在网线拔出的情况下获取不到MAC,而 SNMP 方法有时会获取多个重复的网卡的MAC,试来试去还是 GetAdaptersInfo 方法比较好,网线拔出的情况下可以获取MAC,而且很准确,不会重复获取网卡。
GetAdaptersInfo 方法也不是十全十美,也存在些问题:
1)如何区分物理网卡和虚拟网卡;
2)如何区分无线网卡和有线网卡;
3)“禁用”的网卡获取不到。
关于问题1和问题2我的处理办法是:
区分物理网卡和虚拟网卡:pAdapter->Description中包含"PCI"是:物理网卡。(试了3台机器可以)
区分无线网卡和有线网卡:pAdapter->Type为71的是:无线网卡。(试了2个无线网卡也可以)
