小弟刚学socket编程，搞了个程序（如下），可是编译总出现system.net.sockets.socket并不包含socket的错误信息
我用的是Visual C# 2005编译器，那位高手能给指点迷津？先谢了！
//example
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
public class Class1
{
      public string DoSocketGet(string server){
          Encoding ASCII=Encoding.ASCII;
          string Get="GET/HTTP/1.1\r\nHost:"+server+"\r\nConnection:Close\r\n\r\n";

          Byte[] ByteGet=ASCII.GetBytes(Get);
          Byte[] RecvBytes=new Byte[256];
          String strRetPage=null;
          IPAddress hostadd=Dns.GetHostEntry(server).AddressList[0];
          IPEndPoint EPhost=new IPEndPoint(hostadd,80);

          Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
          s.Socket(EPhost);
          if(!s.Connected){
                       strRetPage="无法连接主机!";
                       return strRetPage;
          }
          
          s.Send(ByteGet,ByteGet.Length,SocketFlags.None);
          Int32 bytes=s.Receive(RecvBytes,RecvBytes.Length,0);
          strRetPage="Default HTML page on"+server+":\r\n";
          strRetPage=strRetPage+ASCII.GetString(RecvBytes,0,bytes);

          while(bytes>0){
                 bytes=s.Receive(RecvBytes,RecvBytes.Length,SocketFlags.None);
                 strRetPage=strRetPage+ASCII.GetString(RecvBytes,0,bytes);
          }
          return strRetPage;
     }  
}
