Name	Type	Description
pattern	Appointment	An Appointment object that is the pattern of the recurrent series.

Returns

Type	Description
TimeInterval	A TimeInterval object that is the time interval occupied by the appointment series.

Example

The following code sample retrieves the recurrence pattern of the first appointment in the scheduler’s collection and calculates the time interval of the recurrent series.

Form1.cs

// Calculate a time interval occupied by the first recurrent series.
Appointment pattern = schedulerStorage1.Appointments.Items.FirstOrDefault(item => item.Type == AppointmentType.Pattern);
if (pattern == null) return;
OccurrenceCalculator calc = OccurrenceCalculator.CreateInstance(pattern.RecurrenceInfo);
TimeInterval ti = calc.CalcSequenceInterval(pattern);
MessageBox.Show(ti.ToString(), "Time Interval of the First Recurrent Series");

Form1.vb

' Calculate a time interval occupied by the first recurrent series.
Dim pattern As Appointment = schedulerStorage1.Appointments.Items.FirstOrDefault(Function(item) item.Type = AppointmentType.Pattern)
If pattern Is Nothing Then
    Return
End If
Dim calc As OccurrenceCalculator = OccurrenceCalculator.CreateInstance(pattern.RecurrenceInfo)
Dim ti As TimeInterval = calc.CalcSequenceInterval(pattern)
MessageBox.Show(ti.ToString(), "Time Interval of the First Recurrent Series")
