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
