今天我想實現數據庫連接的存儲庫模式+工作模式單元。我的代碼是否正確?因爲這是我第一個實現數據庫連接的工作單元。存儲庫使用MVC應用程序中的數據庫的UnitOfWork模式
一庫:
public class NotesRepository : INotesRepository
{
private DatabaseContext context;
public NotesRepository(DatabaseContext context)
{
this.context = context;
}
public IQueryable<Notes> GetAllNotes()
{
return (from x in context.Notes
select x);
}
}
二庫:
public class UnitOfWork
{
private DatabaseContext context = new DatabaseContext();
private INotesRepository notesRepository;
private ICommentsRepository commentsRepository;
public INotesRepository NotesRepository
{
get
{
if (this.notesRepository == null)
{
this.notesRepository = new NotesRepository(context);
}
return notesRepository;
}
}
public ICommentsRepository CommentsRepository
{
get
{
if (this.commentsRepository == null)
{
this.commentsRepository = new CommentsRepository(context);
}
return commentsRepository;
}
}
}
和控制器中,我可以使用單多庫:
public class CommentsRepository : ICommentsRepository
{
private DatabaseContext context;
public CommentsRepository(DatabaseContext context)
{
this.context = context;
}
public IQueryable<Comments> GetAllComments()
{
return (from x in context.Comments
select x);
}
}
數據庫連接工作類單位數據庫連接:
public class HomeController : Controller
{
private UnitOfWork unitOfWork = new UnitOfWork();
public ViewResult Index()
{
var a = unitOfWork.NotesRepository.GetAllNotes();
var b = unitOfWork.CommentsRepository.GetAllComments();
return View();
}
}
