?用何名称区分不同的网卡?
?有如下名称可供选择?
????本地连接名,?这是系统使用的方法,?调用的是netman.dll中的未公开函数HrLanConnectionNameFromGuidOrPath(其原型笔者正在调试之中,?成功之后会另行撰文); 其实也可从注册表中获得HKLMSystemCurrentControlSetControlNetwork{4D36E972-E325-11CE-BFC1-08002BE10318}{97EFDAD8-EB2D-4F40-9B07-0FCD706FCB6D}ConnectionName?
????网卡类型描述?
????设备友好名????????它与网卡类型描述基本相同,?当存在同种类型的网卡,?它会加#n(n?=?2,?3,?4...)以示区分?
????如本程序中笔者即以设备友好名区分网卡?
