网络编程：获取本机主机名和IP地址

 class Program
    {
        static void Main(string[] args)
        {
            string hostName = Dns.GetHostName();
            Console.WriteLine("本电脑的名字为{0}",hostName);
            IPHostEntry myself = Dns.GetHostByName(hostName);
            foreach (IPAddress IPAddr in myself.AddressList)
            {
                Console.WriteLine("IP Address:{0}",IPAddr);
            }
            Console.ReadLine();
        }
    }
