C#网络编程——IPHostEntry

using System;
using System.Net;

namespace study
{
    class IPHostEntrySample
    {
        public static void func(string argv)
        {
            //获得主机名
            IPHostEntry results = Dns.GetHostByName(argv);
            Console.WriteLine("Host:{0}", results.HostName);

            //使用循环显示IP地址表
            foreach(string alias in results.Aliases)
            {
                Console.WriteLine("Alias:{0}", alias);
            }

            //遍历地址列表
            foreach(IPAddress address in results.AddressList)
            {
                Console.WriteLine("Address:{0}", address.ToString());
            }
        }
    }
}

提供字符串，例如IPHostEntrySample.func("www.qq.com"),返回目标主机信息
