How to get a series of files from an FTP server using C #

I am stuck at the point where I am using a substitution parameter with FtpWebRequest object as suck

   FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + WildCard));

      

        
        
        
      

    

now it works fine, however now I want to get a specific range of files.

say the file naming structure *YYYYMMDD.*

and I need to get all the files up to today.

I was looking for a pattern template for this with no good results that would work on a simple list of files.

and it doesn't look like I can use regex here.

any thoughts?
