using System;
using System.Management;namespace PublicBill.GetMAC
{
    class GetMAC
    {
        [STAThread]
        static void Main(string[] args)
        {
            string mac = "";
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach(ManagementObject mo in moc)
            {
                if(mo["IPEnabled"].ToString() == "True")

                }
            }
            Console.WriteLine("MAC Address: " + mac.ToString());
