获取MAC地址的三种方法

引言

在我之前出的文章中，有一篇获取cpu序列号的文章，文章中我探讨了三种方法，下面我给出获取MAC地址的三种方法，供大家一起学习探讨。其优缺点跟之前CPU的一样，这里不再赘述。经大家测试，第二种、第三种方法有一定局限性，经查资料：wmic命令需要两个先决条件a. 启动Windows Management Instrumentation服务，开放TCP135端口。b. 本地安全策略的“网络访问: 本地帐户的共享和安全模式”应设为“经典-本地用户以自己的身份验证”。

;方法三
GetMacAddress()
{
	NetworkConfiguration := StdoutToVar_CreateProcess("getmac")
	RegExMatch(NetworkConfiguration, ".*?([0-9A-Z].{16})(?!\w\\Device)", mac)
	return %mac1%
