關於在ASP.net中實現N層體系結構的問題MVC

-2

我想在asp.net mvc中實現正確的n層體系結構，但是在[staffController]上有一些問題。關於在ASP.net中實現N層體系結構的問題MVC

這裏是我的代碼：

域

public interface IEntity { 
     int Id { set; get; } // all entities have a ID property 
} 

public interface IStaff : IEntity { 
     string Name { set; get; } // staff entity has NANE 
} 

public class Staff : IStaff { 
     public int Id { get; set; } 
     public string Name { get; set; } 
}

視圖模型

public interface IViewModel { 
    int Id { set; get; } // based on IEntity , all ViewModel have ID too 
} 

public interface IStaffViewModel : IViewModel { 
    string Name { set; get; } 
    string NameId { get; } 
} 

public class StaffViewModel : IStaffViewModel { 
    public int Id { get; set; } 
    public string Name { get; set; } 

    public string NameId 
    { 
     get { return "Name" + Id;} 
    } 
}

通用庫

public interface IRepository<TEntity, out TViewModel> 
          where TEntity : IEntity 
          where TViewModel : IViewModel { 
     TViewModel Load(int id); 
} 

public class Repository : IRepository<IEntity,IViewModel> 
    { 
     public IViewModel Load(int id) 
     { 
      // load from database -> Map entity to Viewmodel and post ViewModel 
     } 
    } 
}

服務

public interface IService<in TEntity, out TViewModel> 
         where TEntity : IEntity 
         where TViewModel : IViewModel { 

    TViewModel LoadEntity(int id); 
} 
public class Service<TEntity, TViewModel> 
         : IService<TEntity , TViewModel> 
         where TEntity : IEntity 
         where TViewModel : IViewModel { 
    private readonly IRepository<TEntity, TViewModel> _repository; 

    public Service(IRepository<TEntity,TViewModel> repository) 
    { 
     _repository = repository; 
    } 

    public TViewModel LoadEntity(int id) 
    { 
     return _repository.Load(id); 
    } 
}

員工服務

public interface IStaffService : IService<IStaff,IStaffViewModel> { } 
public class StaffService : Service<IStaff,IStaffViewModel>, IStaffService 
{ 
    private readonly IRepository<IStaff, IStaffViewModel> _repository; 

    public StaffService(IRepository<IStaff, IStaffViewModel> repository) : base(repository) 
    { 
     _repository = repository; 
    } 
}

基本控制器

public class BaseControlle 
{ 
    private readonly IService<IEntity, IViewModel> _service; 

    public BaseControlle(IService<IEntity,IViewModel> service) 
    { 
     _service = service; 
    } 
}

員工控制器與基地（服務）poroblem

public class StaffController : BaseControlle 
{ 
    public StaffController(IStaffService service) : base(service) 
    { 
     // **I have Problem here with base(service) 
    } 
}

有沒有在我的代碼的任何其他問題？我可以相信這個架構是用於開發企業解決方案嗎

您可能還需要遵守[樓梯模式]（http://stackoverflow.com/questions/29259414/stairway-pattern-implementation），即接口和具體類的分離。另外，在企業級別，您可能需要遵循[SOLID原則]（https://en.wikipedia.org/wiki/SOLID_（object-oriented_design）） – Corak

要回答你的代碼的問題是：你需要讓BaseController通用
：

public class BaseController<TEntity, TViewModel> 
{ 
    private readonly IService<TEntity, TViewModel> _service; 

    public BaseControlle(IService<TEntity, TViewModel> service) 
    { 
     _service = service; 
    } 
} 

public class StaffController : BaseController<IStaff, IStaffViewModel> 
{ 
    public StaffController(IStaffService service) : base(service) 
    { 
    } 
}
