Re: FTP in ASP.NET C#

rex64,

If you have access to .NET 2.0 on the server, then I would create an
FtpWebRequest and then send the file through that. If you don't have access
to this, then I would recommend looking at the Indy Project, located at
(watch for line wrap):

http://www.indyproject.org/

It has native .NET classes that will allow you to use the FTP protocol.

You have to make sure that the user that the ASP.NET page is running
under has access to the network though in order to do this (or any other
network operation, for that matter).

Hope this helps.
