Reliable method to get machine's MAC address in C#        http://stackoverflow.com/questions/850650/reliable-method-to-get-machines-mac-address-in-c-sharp二、解决方法：    using System;    using System.Collections.Generic;    using System.Text;    using System.Net.NetworkInformation;     namespace LocalDetectTest    {        class NetTools        {            ///             /// Finds the MAC address of the NIC with maximum speed.            ///
