问题:

I am trying to create a ftp server in c#. This server should listen to any ftp requests, and if a file is sent from a remote location, then the server should write it to a specific folder. I am using VS2008. Do I need a tcp listener? FtpWebRequest? FtpWebResponse?

回答1:

I believe a TcpListener would be easiest to work with

There's an old article on it here that should still be usefull: codeguru

回答2:

Don't know if writing your own FTP server is the way to go here.

Wouldn't it be easier to install a pre-rolled FTP server, and have a job that polls your FTP upload directory? This job will identify incoming files and then places them where you need based on a set of predefined rules.

Can't you extend IIS ftp service? For example: http://learn.iis.net/page.aspx/673/how-to-use-managed-code-c-to-create-an-ftp-authentication-provider-with-dynamic-ip-restrictions/

Or as you asked: http://learn.iis.net/page.aspx/579/advanced-logging-for-iis-70---custom-logging/
