3 Map 

 

using Nop.Core.Domain.Hotels;

namespace Nop.Data.Mapping.Hotels
{
    public partial class HotelMap : NopEntityTypeConfiguration<Hotel>
    {
        public HotelMap()
        {

4 Services 层

 

using System.Collections.Generic;
using Nop.Core;
using Nop.Core.Domain.Hotels;

namespace Nop.Services.Hotels

        IList<Hotel> GetHotelByIds(int[] hotelIds);

       
        IPagedList<Hotel> GetAllHotels( int pageIndex = 0, int pageSize = int.MaxValue, bool showHidden = false);


        void InsertHotel(Hotel hotel);
