How can I export to CSV in an ASP.NET MVC application?

Question

I know this question has been asked and answered in several ways, but none of them get to the crux of the matter that I need to understand. In WebForms, we 'subvert' the rendering process and write straight to the Response's output stream. How does one achieve that using a Controller Action, to write CSV to a file for Excel?

Answer 1

Same way you'd write any other file -- use FileResult and it's descendants.

Answer 2

I've been using this: http://filehelpers.com/ in an asp.net mvc application, look at the getting started guide, you should get it from there
