c 獲取本地IP和MAC位址
查詢了幾個方法,經過除錯修改,下面這個方法能很好的獲取到本地的ip和mac位址。可以用於這方面的功能實現。主要是要新增system.management的引用。csharp view plain copy print?using system using system.management usin...
linux獲取MAC位址程式設計
1 ifconfig a 其中 hwaddr欄位就是mac位址 2 cat sys class net eth0 address 檢視eth0的mac位址 3 cat proc net arp 檢視連線到本機的遠端ip的mac位址 4 程式中使用 siocgifhwaddr 的ioctl命令獲取ma...
獲取MAC位址
簡單的辦法是在控制台輸入ping 目標ip,然後用 arp a 來檢視.或者下面的 記下來以備後用 private declare function inet addr function inet addr lib wsock32.dll byval s as string as int32 pri...
