i've found these snipplets by googling around and they seem to work
properly:

---------------------------
public static void CopyStream(Stream input, Stream output)
{
    byte[] b = new byte[32768];
    int r;
    while ((r = input.Read(b, 0, b.Length)) > 0)
        output.Write(b, 0, r);
}

public static byte[] StreamToByte(Stream streaminput)
{
    MemoryStream mem = new MemoryStream();
    CopyStream(streaminput, mem);

    return mem.ToArray();
}

--------------------------------

Thanks for the help
