Creating iCal Files in c#

Question

I\'m looking for a good method of generating an iCalendar file (*.ics) in c# (asp.net). I\'ve found a couple resources, but one thing that has been lacking is their support

Answer 1

iCal can be complicated, so I recommend using a library. DDay is a good free solution. Last I checked it didn't have full support for recurring events, but other than that it looks really nice. Definitely test the calendars with several clients.

Answer 2

I use DDay.Ical, its good stuff. Has the ability to open up an ical file and get its data in a nice object model. It says beta, but it works great for us.

Edit Nov 2016

This library has been deprecated, but was picked up and re-released as iCal.NET by another dev.

Answer 3

The easiest way I've found of doing this is to markup your HTML using microformats.

If you're looking to generate iCalendar files then you could use the hCalendar microformat then include a link such as 'Add to Calendar' that points to:

http://feeds.technorati.com/events/[ your page's full URL including the http:// ]

The Technorati page then parses your page, extracts the hCalendar info and sends the iCalendar file to the client.
