Socket,好像也挺简单,可是,真够烦

虽然思路简单,可是实现起来可真麻烦,因为要用到好多类来实现DNS解析,IP辨别,数据格式变换,解码等,比较烦呢
用到了System.Text.Encoding

.Dns
 .Sockets.Socket
 .IPHostEntry
 .IPAddress
 .IPEndPoint
 ..

是不是很麻烦?下面的代码运用Socket建立加接,然后朝目标计算机的指定端口发送GET请求,然后将请求返回的头256数据返回 

using System;
 using .Sockets;
 using ;
 using System.Text;namespace MyControl
 { 
 
     /** <summary>
     /// SocketTest 的摘要说明。
     /// </summary>
     public class SocketTest
     { 
 
         public SocketTest()
         { 
 
             //
             // TODO: 在此处添加构造函数逻辑
             //            
         }
         /** <summary>
         /// 连接SOCKET
         /// </summary>
         /// <param name="Server">服务器名</param>
         /// <param name="Port">端口</param>
         /// <returns></returns>

         { 
 
             Socket HttpSocket=null;
             IPHostEntry HostIp=null;
             HostIp=Dns.Resolve(Server);
             foreach(IPAddress TempIp in HostIp.AddressList)
             { 
 
                 IPEndPoint Iep=new IPEndPoint(TempIp,Port);
                 Socket TempSocket=new Socket(Iep.AddressFamily,SocketType.Stream,ProtocolType.Tcp);
                 TempSocket.Connect(Iep);
                 if(TempSocket.Connected)
                 { 
 
                     HttpSocket=TempSocket;
                     break;
