C++ 硬體資訊 擷取網卡MAC地址，網卡mac

擷取電腦網卡MAC地址的方法很多，這裡採用的是命令列的形式擷取，可以擷取有線網卡與無線網卡的MAC地址，很簡單，直接

上代碼。

char lpszMac[128] = {0};//擷取MACGetMacByCmd(lpszMac);//列印出MACcout << lpszMac << endl;

【已解決】分享 一段代碼：AIR 讀取硬體網卡MAC地址與IP地址資訊（一個術語）
用c#來獲得電腦使用中的網卡硬體的MAC地址

嘿嘿，我每次就直接在開始|運行裡，擷取的所有的MAC地址了也。
不知道有沒有你所說的虛擬網卡呢。

開始|運行|輸入“cmd”|再輸入“ipconfig -all”，斷行符號就行。
