BinaryReader should work indeed:

BinaryReader br = new BinaryReader(fStream);

byte[] bdata = br.ReadBytes((int)numBytes);

br.Close();

fStream.Close();

// Write bdata to the HttpStream
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("url-here");
// Additional webRequest parameters settings.
HttpStream stream = (Stream)webRequest.GetRequestStream();
stream .Write(bdata, 0, bdata.Length);
stream.Close();

HttpWebResponse response = (HttpWebRewponse)webRequest.GetResponse();
