问题描述
我正在考虑将有线MAC-adr用作程序中的唯一值.因此，我需要确保MAC-adr是有线的，而不是无线的.
I am thinking about using the wired MAC-adr as a unique value in a program. So i need to be sure the MAC-adr is the wired one and NOT the wireless.
$mac = gwmi -computer $compname win32_NetworkAdapterConfiguration | select MACAddress
这是我开始的目的，但是它给了我两个地址.第一个是我想要的一个:00:00:11:11:22:22最后一个是无线地址:00:1F:3C:8E:61:D8
This is what I started with, but it gives me two addresses.First one is the one I want: 00:00:11:11:22:22The last one is the wireless address: 00:1F:3C:8E:61:D8
我不能像这样排序:选择-first 1.因为我不知道这会导致我在其他计算机上工作.顺便说一句，这个功能在ipV6和ipV4上都可以使用吗?
I can't just sort like: select -first 1. Because I don't know what this will get me on other computers..And btw, this DOES work on ipV6 as well as ipV4?
推荐答案
尝试这种方式:
$mac = gwmi -computer $compname win32_NetworkAdapter | ? { $_.AdapterType -match "802.3" } | select MACAddress
如果有多个，则需要进行选择.
If there's more than one you need to do a selection.
