Question

Why downloaded PDF file have different size and content than the source PDF file ?

The files content and the source code attached.

Regards , Alex

Code:

ExFTPConnection.DataEncoding = Encoding.GetEncoding(1255);

MemoryStream MS = new MemoryStream();

ExFTPConnection.DownloadStream(MS, FtpFileName);

Answer 1

Try explicitly setting to binary mode transfer prior to calling DownloadStream.

This is problem - in binary mode i get  file size x 2 (UTF8) and
if i do not set DataEncoding correct i don't  get correct  charset to text files, except english.
Why DataEncoding affect to download/upload process in binary mode.
