        /// <returns></returns>
        public static string GetNetCardIP()
        {
            try
            {
                string stringIP = "";
                ManagementClass MC = new ManagementClass("Win32_NetworkAdapterConfiguration");
                ManagementObjectCollection MOC = MC.GetInstances();
                foreach (ManagementObject MO in MOC)
                {
                    if ((bool)MO["IPEnabled"] == true)
                    {
                        string[] IPAddresses = (string[])MO["IPAddress"];
                        if (IPAddresses.Length > 0)
                        {
                            stringIP = IPAddresses[0].ToString();
                        }
                    }
                }
                return stringIP;
            }
            catch

                return "";
            }
        }

class Program    {        static void Main(string[] args)        {            Console.WriteLine(GetLocalHostIPAddress());            Console.ReadLine();        }        static string GetLocalHostIPAddress()        {            IPAddress[] ipLocal;//定义一个IPAddress类型的数组,用来存储本地IP            byte[] bArrIPAddr;//定义一个byte类型的数组,用来把存储字节型IP地址形式            int intI;            string strIPAddr = "";            ipLocal = Dns.GetHostAddresses(Dns.GetHostName());//通过本机名获取本机IP地址            if (ipLocal.Length == 0)            {                return strIPAddr;            }            bArrIPAddr = ipLocal[0].GetAddressBytes();            /*             * byte[]IPAddress.GetAddressBytes()             * Provides a copy of the System.Net.IPAddress as an array of bytes.            */            intI = 0;            while (intI < bArrIPAddr.Length)            {                if (intI == 0)                {                    strIPAddr = bArrIPAddr[intI].ToString();                }                else                {                    strIPAddr += "." + bArrIPAddr[intI].ToString();                }                intI += 1;            }            return strIPAddr;        }    }
