C# Socket Http请求

在网上搜寻了半天没有查到C# socket发送http请求（java的倒是有一篇也很含蓄），于是自己根据http协议规范写了个C#的http socket请求。

class Program         static void Main(string[] args)             byte[] data = new byte[1024];
            string input, stringData;
            IPHostEntry gist = Dns.GetHostByName("www.baidu.com");

            IPAddress ip = gist.AddressList[0];     //得到IP
            IPEndPoint ipEnd = new IPEndPoint(ip, 80);//默认80端口号
            Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//使用tcp协议 stream类型 
            try                 socket.Connect(ipEnd);             catch (SocketException e)                 Console.Write("Fail to connect server");
                Console.Write(e.ToString());
                return;             string path = "/index.php";//这里请求的相对地址，如果访问直接www.baidu.com则不需要为空.
            StringBuilder buf = new StringBuilder();
            buf.Append("GET ").Append(path).Append(" HTTP/1.0\r\n");
            buf.Append("Content-Type: application/x-www-form-urlencoded\r\n");
            buf.Append("\r\n");
            byte[] ms = System.Text.UTF8Encoding.UTF8.GetBytes(buf.ToString());

            socket.Send(ms);

            int recv = -1;
            do                 recv = socket.Receive(data);
                stringData = Encoding.UTF8.GetString(data, 0, recv);//如果请求的页面meta中指定了页面的encoding为gb2312则需要使用对应的Encoding来对字节进行转换
                Console.Write(stringData);

            } while (recv != -1);
            Console.Write("disconnect from server");
            socket.Shutdown(SocketShutdown.Both);
            socket.Close();
        }

    }
