using System;
using System.Net;

namespace GetIpAndName
{

 class Class1
 {
 
  [STAThread]
  static void Main(string[] args)
  {
   //得到主机名
   string name = Dns.GetHostName();
   Console.WriteLine("主机名字：{0}",name);

   IPHostEntry me = Dns.GetHostByName(name);

   //输出得到的IP
   foreach (IPAddress ip in me.AddressList)
   {
    Console.WriteLine("IP  地址：{0}",ip.ToString());
   }
   Console.Read();
  
  }
 }
}
