if (rgFiles.Count() > 0)
{
foreach (FileInfo fi in rgFiles)

Answer 1

You can't access a directory residing on the web with the DirectoryInfo class. Instead, use the WebRequest class to get a list from the URL and get the files from that list.

Answer 2

DirectoryInfo need a UNC path of type "\\fileserver\images"

A http address will not work

Answer 3

The problem is that HTTP does not have a clear interface on how a directory listing is being displayed. There are roughly two choices:

1. Parse the HTML retrieved through a WebRequest, but you won't get things like creation/modification time and user;

2. Go with a different mechanism to retrieve the file details like FTP or File share.
