小编Joh*_*ado的帖子

我是asp.net mvc的新手.

我正在使用Linq到Sql并试图做松散耦合的一切.

我有两张桌子:

1. 新闻
2. NewsFiles

我要做的是保存新闻并同时上传文件.

如何与他的文件一起创建新闻,将其保存到NewsFiles表？

Linq to Sql模型没问题,它包含对象NewsFile到News对象.

我的新闻表的具体存储库类(葡萄牙语中的noticia):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MagixCMS.Models
{
    public class NoticiaRepository : INoticiaRepository
    {
        #region INoticiaRepository Members

        magixcmsEntities _entities = new magixcmsEntities();

        public noticia CreateNoticia(noticia noticiaToCreate)
        {
            _entities.AddTonoticiaSet(noticiaToCreate);
            _entities.SaveChanges();
            return noticiaToCreate;
        }

        public void DeletaNoticia(noticia noticiaToDelete)
        {
            var noticiaOriginal = GetNoticia(noticiaToDelete.Id);
            _entities.DeleteObject(noticiaOriginal);
            _entities.SaveChanges();
        }

        public noticia EditNoticia(noticia noticiaToEdit)
        {
            var noticiaOriginal = GetNoticia(noticiaToEdit.Id);
            _entities.ApplyPropertyChanges(noticiaToEdit.EntityKey.EntitySetName, noticiaToEdit);
            _entities.SaveChanges();
            return noticiaToEdit;
        }

        public noticia GetNoticia(int id)
        {
            return …
