Public Function GetAppointments(
    start As Date,
    end As Date,
    useCache As Boolean = False
) As AppointmentBaseCollection


Name Type Description
start DateTime

A System.DateTime value that specifies the start time of the required time interval.

end DateTime

A System.DateTime value that specifies the end time of the required time interval.

Optional Parameters

Name Type Default Description
useCache Boolean


True, to use the appointment cache to increase performance. When set to false, enables you to operate with SchedulerStorage in multiple threads, since different requests for appointments will not use the same cache.


Type Description

An AppointmentBaseCollection collection of appointments which belong to the specified time interval.


The GetAppointments method returns standard appointments and occurrences (appointments created based upon recurring pattern appointments), that belong to the specified time interval. If an appointment's time interval partially overlaps the specified interval, this appointment is also included in the collection returned.


The end parameter's value should be greater than or equal to the start parameter's value, otherwise an exception will be thrown.

The GetAppointments method gets appointments contained in the storage and passed through filters. Appointment filters are the AppointmentStorageBase.Filter property and the SchedulerStorageBase.FilterAppointment event.


In multi-threaded applications use the GetAppointments method with useCache parameter set to false
