SslStream read all bytes

When i am try to read from SslStream function Read() is never end if i am not set connection timeout but if i do i've got timeout exception. This guy have the same problem http://msdn.microsoft.com/en-us/library/system.net.security.sslstream.read.aspx. I don't what to do here the code 

    public byte[] ReadBytes()
    {
        this.bufferGlobal.Clear();
        byte[] buffer = new byte[this.bufferSize];
        int recv = this.stream.Read(buffer, 0, buffer.Length);
        while (recv != 0)
        {
            addBytes(buffer, ref bufferGlobal, recv);
            recv = this.stream.Read(buffer, 0, buffer.Length);                
        }
        return (byte[])this.bufferGlobal.ToArray(typeof(byte));
    }

Thx in advance.

UPD:

i think i find the answer. I can set read timeout on SslStream equal one, thats value does not make sense for socket alive (its mean you can download huge files and don't worry about SslStream he wouldn't close connection or interupt recieve data). I just testing this solution but seems works fine. Thx everybody.

please use this working patch if it works for you:

                int bytesRead = 0;
                string chunkString = "";
                do
                {
                    byte[] responseBuffer = new byte[CHUNKSIZE];
                    bytesRead = sslStream.Read(responseBuffer, 0, responseBuffer.Length);
                    ApplicationHelper.ApplicationLogger.WriteInfoLog("Bytes Received " + bytesRead);
                    if (bytesRead > 0)
                    {
                        chunkString = Encoding.UTF8.GetString(responseBuffer, 0, bytesRead);
                        responseXML += chunkString;
                    }

                }
                while (!chunkString.EndsWith(EOF));

bit late but I am using msdn code with following modification 

if (sb.ToString().IndexOf("a OK") != -1 || sb.ToString().IndexOf("a BAD") != -1 || sb.ToString().IndexOf("a NO") != -1)
            {
                break;
            }

The stream won't end until the connection is closed. This is the nature of all streams of an unknown length.

You either need to know the length ahead of time or you need to keep reading until the connection is closed. A common way is to transmit the byte length of the stream as a 64bit int. So the first 8 bytes of your stream is read into an int64, then the rest is the data.

Typically one reads in a stream one "buffer" at a time.

pseudo code

while(!Stream.end) { i = Stream.Read(buffer, buffer.length) DestStream.Write(buffer, i) }

You are reading from a network stream, which means you will not encounter the end of stream until the other side closes its half of the connection. It isn't enough for it to stop sending data. So, make your other program close the connection after it has sent all data it intends to.
