Export SQL Data to Flat File in ASP.NET

I need to create an simple web app that will allow our client to query a SQL database and then export the returned recordset to a flat file.

I am using ASP.NET to develop this app.

In ASP.NET, how can I take a returned recordset and save the info to a flat file on the user’s computer?

Any help would be greatly appreciated.

Thanks!
