How to generate user friendly message based on icalendar format

Question

Lets say we have recurrence rule like this one:

RRULE:FREQ=MONTHLY;BYDAY=-2FR;COUNT=7

My question is how to generate user friendly text from RRULE like this: every month on the 2nd last Friday for 7 times

Are there any .net c# libs, which allow to achieve that?

Answer 1

This one helped me. EWSoftware.PDI library contains Recurrence class with ToDescription method, which generates plain text description based on provided RRULE.

var recurrence = new Recurrence("FREQ=MONTHLY;BYDAY=-2FR;COUNT=7")
{
    StartDateTime = startDate
};

var description = recurrence.ToDescription();

Output: Recur every month on the 2nd last Friday for 7 times
