Returns a collection of objects that will be saved when the current transaction is committed.
The collection of persistent objects that will be saved when the current transaction is committed.
For general information on saving persistent objects, see Persisting Objects.
Objects that have Deferred Deletion enabled are actually modified upon deletion. So, they appear in the collection returned by the Session.GetObjectsToSave method, not in the collection returned by the Session.GetObjectsToDelete method.
The Session.GetObjectsToSave and Session.GetObjectsToDelete methods do not create new collection instances and fill them with objects when called. Instead, these methods return references to internal collections whose content changes throughout the life cycle of a Session.
ICollection changedObjects = myUnitOfWork.GetObjectsToSave(); int count = changedObject.Count; // 'count' is an arbitrary number myUnitOfWork.CommitChanges(); count = changedObject.Count; // here, 'count' always equals zero
