Answer 1

The code you have above does not create a proper multipart body.

You can't simply write the file into the stream, each part requires a preamble boundary marker with per-part headers, etc.

See Upload files with HTTPWebrequest (multipart/form-data)

Answer 2

Some informations about your multiple contentTypes problem here : http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.7.2

multipart/form-data is the only way to send multiples data types over http protocol.
