C＃如何用冒号获取mac地址

Question

代码：

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

输出：

  

0800275283A8

如何隐蔽：

  

08：00：27：52：83：A8

Answer 1

试试这个：

 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
