[Mono-dev] Bug In Mono FTP System.Net.FtpWebRequest

[Dieuzorro]

With my code I was able to download a file on the server
"ftp://ftp-developpez.com/konflor/Latex/formation/FormationLatex.pdf"
anonymously. But on my local server when I want to download a file with a
loggin and a password, my stream "ResponceStream" is empty and there is no
error. On Windows everything works.

      Have you got an exemple on mono which connect on an private ftp
server? But my code works on windows and ftp server!

    Thanks
