| 32-33 | Error in Code Example The code sample should look like this: using System; using System.Collections.Generic; using SmartCA.Infrastructure.DomainBase; using SmartCA.Infrastructure.RepositoryFramework; using System.Transactions; namespace SmartCA.Infrastructure { public class UnitOfWork : IUnitOfWork { private Dictionary<EntityBase, IUnitOfWorkRepository> addedEntities; private Dictionary<EntityBase, IUnitOfWorkRepository> changedEntities; private Dictionary<EntityBase, IUnitOfWorkRepository> deletedEntities; public UnitOfWork() { this.addedEntities = new Dictionary<EntityBase, IUnitOfWorkRepository>(); this.changedEntities = new Dictionary<EntityBase, IUnitOfWorkRepository>(); this.deletedEntities = new Dictionary<EntityBase, IUnitOfWorkRepository>(); } #region IUnitOfWork Members public void RegisterAdded(EntityBase entity, IUnitOfWorkRepository repository) { this.addedEntities.Add(entity, repository); } public void RegisterChanged(EntityBase entity, IUnitOfWorkRepository repository) { this.changedEntities.Add(entity, repository); } public void RegisterRemoved(EntityBase entity, IUnitOfWorkRepository repository) { this.deletedEntities.Add(entity, repository); } public void Commit() { using (TransactionScope scope = new TransactionScope()) { foreach (EntityBase entity in this.deletedEntities.Keys) { this.deletedEntities[entity].PersistDeletedItem(entity); } foreach (EntityBase entity in this.addedEntities.Keys) { this.addedEntities[entity].PersistNewItem(entity); } foreach (EntityBase entity in this.changedEntities.Keys) { this.changedEntities[entity].PersistUpdatedItem(entity); } scope.Complete(); } this.deletedEntities.Clear(); this.addedEntities.Clear(); this.changedEntities.Clear(); } #endregion } } the actual code files for the chapter are correct |
