ASP.net script to create CSV file

Question

Hi,

I have a PHP script which writes a CSV file when a form is submitted from my Flash application.

I need the same script for a Microsoft server so if this can be done in Asp.NET, I would appreciate it if someone knows where I can find something like this? What I need it to do is to update the CSV file every time someone submits the form and writes it to a specific folder on the server. At a later stage I need to be able to download the CSV and send it onto my client.

Something like this (http://www.tectite.com/fmhowto/csvfiles.php) but for Asp.NET

Thanks, James
