Question

獲取MAC地址代碼：

var macAddr = 
     (from nic in NetworkInterface.GetAllNetworkInterfaces() 
     where nic.OperationalStatus == OperationalStatus.Up 
     select nic.GetPhysicalAddress().ToString()).FirstOrDefault(); 

輸出：

0800275283A8

如何隱蔽到：

08:00 ：27：52：83：A8

Answer 1

試試這個：

var macAddr = 
       (from nic in NetworkInterface.GetAllNetworkInterfaces() 
       where nic.OperationalStatus == OperationalStatus.Up 
       select nic.GetPhysicalAddress().GetAddressBytes()).FirstOrDefault(); 

string formattedMacAddr = string.Join (":", (from z in macAddr select z.ToString ("X2")).ToArray()); 
Console.WriteLine(formattedMacAddr); 

//outputs this format: 08:00:27:52:83:A8
