i'm stuck at a point where i am using a wildcard parameter with the FtpWebRequest object as suck
FtpWebR开发者_开发问答equest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + WildCard));
now this works fine, however i now want to fetch a specific range of files.
say the file naming structure is *YYYYMMDD.*
and i need to fetch all the files prior to today's date.
i've been searching for a wildcard pattern for that with no good results, one that will work in a simple file listing.
and it doesn't look like i can use regex here.
any thoughts ?
The FTP RETR
(retrieve) command does not support wild cards.
You will have to get a LIST
of all files, loop over them and retrieve only the ones that follow the pattern you need.
RFC 959 does not specify wild cards, but simply states a <pathname>
should be passed to the RETR
command.
