Watch for files in a folder in VB.net

Question

I need to watch a folder in our network and if any files get dropped in any time of the day I need to ftp to a different folder.

What do you think is a feasible approach? Please post links if you have any that will take me in right direction.

Answer 1

Best bet might be the filewatcher component. Seems to work reasonable well over the network.

Answer 2

Use System.IO.FileSystemWatcher to watch the folder: Listens to the file system change notifications and raises events when a directory, or file in a directory, changes.

Use System.Net.FtpWebRequest to send the file through FTP.

Answer 3

To watch the file system, the (aptly named) FileSystemWatcher is a useful option. There are many reports of unreliability however, so polling periodically is important.

See this question for a small "Polling vs FileSystemWatcher" debate.

As far as the FTP upload goes, as Alfred says, FtpWebRequest should do what you need.

Answer 4

FileSystemWatcher as mentioned by the others will work fine in most cases, but not on Novell network drives.
