tcp client

Hi, I'm working on a C# tcp client that will make a simple http request. Here's my code so far:



            string http;
            http = "GET /2008/10/02/android-the-next-wave/ HTTP/1.1\r\n";
            http += "Host: www.solutionbot.com\r\n";
            http += "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3 (.NET CLR 3.5.30729)\r\n";
            http += "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\nAccept-Language: en-us,en;q=0.5\r\n";
            http += "Accept-Encoding: gzip,deflate\r\n";
            http += "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\nKeep-Alive: 300\r\nConnection: keep-alive\r\nCache-Control: max-age=0\r\n\r\n";



            Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            client.Connect("www.google.com", 80);

            NetworkStream ns = new NetworkStream(client);

            StreamWriter sw = new StreamWriter(ns);

            sw.Write(http);
            sw.Flush();

            string buffer = "";
            int k = client.ReceiveBufferSize;
            Byte[] bb = new Byte[k];

            int i = ns.Read(bb, 0, k);

            buffer = Encoding.UTF8.GetString(bb);

            while (true)
            {
                int j = ns.ReadByte();

                if (j == -1) break;

                char c = (char)j;
                buffer += c.ToString();
            }

 
           
            client.Close();

            string headers = buffer.Substring(0, buffer.IndexOf("\r\n\r\n"));
            string content = buffer.Substring(buffer.IndexOf("\r\n\r\n"));

            textBox1.Text = buffer;


the problem with this code is the fact that it is really slow (for obvious reasons). It reads one byte at a time. The reason for this is because the buffer size isn't the entire amount of data that gets sent over. I can't seem to find any other method though. I don't want to use the httpwebrequest as i really like the flexability of the sockets class. Can anyone help?

actually...take a look at MSDN:

http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.aspx

you can use the following instead:

int bytes = 0;
do {
            bytes = s.Receive(bytesReceived, bytesReceived.Length, 0);
            page = page + Encoding.ASCII.GetString(bytesReceived, 0, bytes);
        }
        while (bytes > 0);

If you still find it slow, you may want at making it asynchronous:
