C# 擷取網卡MAC的兩種方式

標籤：

擷取網卡MAC第一種

不能判斷當前使用的是那張網卡

 1         /// <summary> 2         /// 擷取網卡ID代碼  3         /// </summary> 4         /// <returns></returns> 5         public static string GetNetworkAdpaterID() 6         { 7             NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces(); 8             return nics[0].GetPhysicalAddress().ToString(); 9 10         }

擷取網卡MAC第二種

可以判斷出來當前使用的是哪張網卡 但是要引入

using System.Management;

        /// <summary>        /// 擷取網卡ID代碼         /// </summary>        /// <returns></returns>        public static string GetNetworkAdpaterID()        {            try            {                string mac = "";                ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");                ManagementObjectCollection moc = mc.GetInstances();                foreach (ManagementObject mo in moc)                    if ((bool)mo["IPEnabled"] == true)                    {                        mac += mo["MacAddress"].ToString();                        break;                    }                string[] macs = mac.Split(‘:‘);                mac = "";                foreach (string m in macs)                {                    mac += m;                }                moc = null;                mc = null;                return mac.Trim();            }            catch (Exception e)            {                return "uMnIk";            }        }
