System.Object

Remarks

Corresponds to a collection of RRULE or EXRULE parts of a recurrence pattern.

Example

Every 20th Monday of the year, forever:

[C#]

//Create the pattern programmatically.
RecurrencePattern pattern = new RecurrencePattern();
pattern.StartDate = new DateTime(1997, 5, 19, 9, 0, 0);
RecurrenceRule rule = pattern.RRules.Add();
rule.Frequency = Frequency.Yearly;
rule.ByDay.Add(20, DayOfWeek.Monday);

DateCollection dates = pattern.GenerateOccurrences(
    new DateTime(1997, 5, 19, 9, 0, 0), 
    new DateTime(1999, 5, 17, 9, 0, 0));

foreach (DateTime d in dates)
    Console.WriteLine(d);

...

//Create the pattern from iCalendar string.
RecurrencePattern pattern = new RecurrencePattern(
    "DTSTART;TZID=US-Eastern:19970519T090000\n" +
    "RRULE:FREQ=YEARLY;BYDAY=20MO");

DateCollection dates = pattern.GenerateOccurrences(
    new DateTime(1997, 5, 19, 9, 0, 0), 
    new DateTime(1999, 5, 17, 9, 0, 0));

foreach (DateTime d in dates)
    Console.WriteLine(d);

[VB]

'Create the pattern programmatically.
Dim pattern As RecurrencePattern = New RecurrencePattern
pattern.StartDate = New DateTime(1997, 5, 19, 9, 0, 0)
Dim rule As RecurrenceRule = pattern.RRules.Add()
rule.Frequency = Frequency.Yearly
rule.ByDay.Add(20, DayOfWeek.Monday)

Dim dates As DateCollection = pattern.GenerateOccurrences( _
    New DateTime(1997, 5, 19, 9, 0, 0), New DateTime(1999, 5, 17, 9, 0, 0))

For Each d As DateTime In dates
    Console.WriteLine(d)
Next

...

'Create the pattern from iCalendar string.
Dim pattern As RecurrencePattern = New RecurrencePattern( _
    "DTSTART;TZID=US-Eastern:19970519T090000" + ControlChars.CrLf + _
    "RRULE:FREQ=YEARLY;BYDAY=20MO")

Dim dates As DateCollection = pattern.GenerateOccurrences( _
    New DateTime(1997, 5, 19, 9, 0, 0), New DateTime(1999, 5, 17, 9, 0, 0))

For Each d As DateTime In dates
    Console.WriteLine(d)
Next
