C# 获得IPV4地址

            IPAddress[] ips = Dns.GetHostAddresses(Dns.GetHostName());
            //txtlocalIP.Text = ips[0].ToString();  
            IPAddress ip;          
            foreach (IPAddress ipa in ips)
            {
                if (ipa.AddressFamily == AddressFamily.InterNetwork)
                {
                    ip = ipa;
                    break;
                }
            }

获得IPV4地址

用以下两种方法都可以的到全部的ip地址。

class Program
    {
        static void Main(string[] args)
        {
            //IPHostEntry ips = Dns.GetHostEntry(Dns.GetHostName());
            //foreach (IPAddress ip in ips.AddressList)
            //{
            //    Console.WriteLine( ip+"  " );
            //}
            IPAddress[] ips = Dns.GetHostAddresses(Dns.GetHostName());
            foreach (IPAddress ip in ips)
            {
                Console.WriteLine(ip);
            }
            Console.ReadKey();
        }
    }
