.net SOCKET发送请求获取不到数据

namespace SocketForm

    public class HttpServer

        private static List<Socket> socket = new List<Socket>();//存闲置SOCKET
        private Socket currentSocket;//当前正在用的SOCKET
        private String url;//地址
        private List<String> cookie;//cookie
        private List<String> param;//参数
        private String method;//方式
        public HttpServer() 
        {
            if (socket.Count > 0)
            {
                currentSocket = socket[0];
                socket.RemoveAt(0);//从池中删掉

            }
        }

        {
            this.url = url;
            this.param = param;
            this.cookie = cookie;
            this.method = "get";
            String address = conect();//建立建连并分离地址
            //HTTP头

            if (cookie != null)

        }
            /**

         **/
        public List<byte[]> send(out long count) 
        {
            count = 0L;
            List<byte[]> b = new List<byte[]>();
            this.currentSocket.Send(Encoding.UTF8.GetBytes("/r/n"));//发送请求头结否标记
            //接收消息
            int bytes;
            do{//**********这里获取不到数据，执行到这里会阻塞几秒，最后返回0******8//////
                byte[] recvBytes = new byte[1024];
                bytes = this.currentSocket.Receive(recvBytes, recvBytes.Length, 0);//从服务器端接受返回信息
                b.Add(recvBytes);
                count += bytes;
                Thread.Sleep(100);
             } while (bytes!=0);
            return b;
        } 

        /**
         * 检查是否已建立SOCKET连接
         **/
        private String conect() 
        {
            String host = this.url.Substring(0, this.url.IndexOf("/") < 0 ? this.url.Length : this.url.IndexOf("/"));
            if (this.currentSocket.RemoteEndPoint == null)
            {
                this.currentSocket.Connect(Dns.GetHostAddresses("www.baidu.com"), 80);
            }
            return this.url.Substring(host.Length).Length>0?this.url.Substring(host.Length):"/";
        }
    }
}

下面是调用代码

HttpServer s = new HttpServer();
            s.get("www.baidu.com",null,null);
            long count;
            List<byte[]> b = s.send(out count);
            for (int i = 0; i < b.Count; i++)
            {
                count -= b[i].Length;
                if (count > 0)
                {
                    System.Console.WriteLine(Encoding.Default.GetString(b[i], 0, b[i].Length));
                }
                else 
                {
                    System.Console.WriteLine(Encoding.Default.GetString(b[i], 0,(int)(b[i].Length-count)));
                }
            }
