Reading File Properties Via FTP without Downloading it.

First of all, to work with FTP as a client, you will need to use the class System.Net.FtpWebRequest:
http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest%28v=vs.110%29.aspx[^].

Then you will need to use proper System.Net.FtpWebRequest.Method. Please see:
http://msdn.microsoft.com/en-us/library/system.net.webrequestmethods.ftp%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.webrequestmethods.ftp.getfilesize(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.webrequestmethods.ftp.getdatetimestamp(v=vs.110).aspx[^].

Probably, from what you wanted to get, you can retrieve the size and only one time property, time stamp.
