“System.Net.Dns.GetHostByName(string)”已过时之类问题解决总结
程序出现: 警告 1 “System.Net.Dns.GetHostByName(string)”已过时:“GetHostByName is obsoleted for this type, please use GetHostEntry instead. http://go.microsoft.com/fwlink/?linkid=14202”
当从VS2003升级到vs2005,或者vs2005到vs2008,vs2010，经常遇到一些警告过时，此类问题解决主要看提示：GetHostByName is obsoleted for this type, please use GetHostEntry instead. GetHostByName类型已经过时，请用GetHostEntry代替，其它类似问题都可以这样解决。

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;

namespace CNetwork
{
    class DNSName
    {
        public static void Main()
        {
            string hostName = Dns.GetHostName();
            Console.WriteLine("Local hostname: {0}", hostName);
            //IPHostEntry myself = Dns.GetHostEntry(hostName);
            IPHostEntry myself = Dns.GetHostByName(hostName);// Dns.GetHostByName(hostName);
          
            foreach (IPAddress address in myself.AddressList)
            {
                Console.WriteLine("IP Address: {0}", address.ToString());
            }
        }

    }
}
