This method adds an Appointment object to the end of the appointment collection maintained by the current AppointmentStorageBase object. This collection can be accessed via the storage's AppointmentStorageBase.Items property.
To prevent excessive updates when changes to the appointment collection are applied, enclose the code that uses the Add method within calls to PersistentObjectStorage<T>.BeginUpdate and PersistentObjectStorage<T>.EndUpdate methods.
In order to perform the same action at the level of the appointment collection, the collection's AppointmentCollection.Add method can be used.
