Deleting Objects
Add the following lines at the end of the code in the last step:
pm.Delete(lstEmployee); pm.Save();
This deletes all Employee objects in the list. You can check it by querying all employees once more:
PersistenceManager pm = new PersistenceManager(); NDOQuery<Employee> q = new NDOQuery<Employee>(pm); if ((decimal)q.ExecuteAggregate("oid", Query.AggregateType.Count) == 0) System.Console.WriteLine("Employees deleted");
