How to create “recurData” in Google Calendar?

Question

I want to create recurring events of Calendar using Google API. I am following links:

1. Google Calendar API

   I am not getting how to create "recurData". I can't modify String and pass it as parameter. Tried DDay.iCal Version 0.80. also.

2. DDay.iCal

There are some Example code given.I tried them. I am able to create ".ics" file.

But when i pass this file content as "recurData"

Getting Error : {"Execution of request failed: http://www.google.com/calendar/feeds/user@domain.com/private/full?gsessionid=AHItK5wrSIoJVawFjGt-0g"}

My icf File content is:

It think this sample will tell us, that you create your Calendar Entry with the EventEntry Class. Then you pass a recurrence to that entry.

In google's example the DTSTART and DTEND Fields are representing the start and end of the recurrence.

EventEntry myEntry = new EventEntry();
myEntry.Title.Text = "Hello recurring Event!";
// Set a location for the event.
Where eventLocation = new Where();
eventLocation.ValueString = "here and there";
entry.Locations.Add(eventLocation);

// Any other event properties

// Recurring event:
String recurData =
  "DTSTART;VALUE=DATE:20070501\r\n" +
  "DTEND;VALUE=DATE:20070502\r\n" +
  "RRULE:FREQ=WEEKLY;BYDAY=Tu;UNTIL=20070904\r\n";

Recurrence recurrence = new Recurrence();
recurrence.Value = recurData;
myEntry.Recurrence = recurrence;
