MVC3.0 EF增删改查的封装类

本人亲身使用EF CodeFirst，因为增删改查都是使用EF内置的一些方法，我想把它封装到一个类调用就行了。结合网上的资料和自己的整理，若有不对的地方望斧正，感激不尽。直接上代码吧。我就用新闻的增删改查做例子。

Models的文件：

1.News.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.ComponentModel.DataAnnotations;

namespace NewsMvc.Models

{

    public class News

    {

        [Display(Name = "编号")]

        public int Id { get; set; }

        [Required(ErrorMessage = "标题必填")]

        [Display(Name = "标题")]

        public string Title { get; set; }

        [Display(Name = "添加人")]

        public string AddUser { get; set; }

        [Display(Name = "内容")]

        public string Content { get; set; }

        [Display(Name = "添加时间")]

        [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}")]

        public DateTime AddDate { get; set; }

        [Display(Name = "备注")]

        public string Remark { get; set; }

        public string tes { get; set; }

    }

}

2.NewsDbContent.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Data.Entity;

namespace NewsMvc.Models

{

    public class NewsDbContent : DbContext

    {

        public DbSet<News> Newss { get; set; }

        public DbSet<NewsType> NewsTypes { get; set; }

    }

}

3.BaseOption.cs（重点来了，这就是封装了EF的增删改查的公共类）

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Data.Entity;

namespace NewsMvc.Models

{

    public class BaseOption<T> where T : class

    {

        NewsDbContent ns_db = new NewsDbContent();

        //添加

        public void Add(T entity)

        {

            ns_db.Entry<T>(entity).State = EntityState.Added;

            ns_db.SaveChanges();

        }

        //修改

        public void Update(T entity)

        {

            ns_db.Set<T>().Attach(entity);

            ns_db.Entry<T>(entity).State = EntityState.Modified;

            ns_db.SaveChanges();

        }

        //删除

        public void Delete(params object[] keyValues)

        {

            T t = FindById(keyValues);

            ns_db.Set<T>().Attach(t);

            ns_db.Entry<T>(t).State = EntityState.Deleted;

            ns_db.SaveChanges();

        }

        //查询集合

        public List<T> getlist(T entity)

        {

            return ns_db.Set<T>().ToList();

        }

        //根据Id返回查询的集合

        public T FindById(params object[] keyValues)

        {

            return ns_db.Set<T>().Find(keyValues);

        }

    }

}

如何使用这个呢，以下是例子：

Controllers文件夹下的文件

NewsController.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using NewsMvc.Models;

using System.Text;

namespace NewsMvc.Controllers

{

    public class NewsController : Controller

    {

        BaseOption<News> bs = new BaseOption<News>();

        //列表页面

        public ActionResult Index()

        {

            News ns = new News();

            return View(bs.getlist(ns));

        }

        //添加

        public ActionResult Create()

        {

            return View();

        }

        //添加

        [HttpPost]

        public ActionResult Create(News ns)

        {

            ns.Title = Request.Form["news_title"].ToString().Trim();

            ns.AddUser = Request.Form["news_adduers"].ToString().Trim();

            ns.Content = Request.Form["news_content"].ToString().Trim();

            ns.AddDate = DateTime.Parse(Request.Form["news_adddate"].ToString().Trim());

            bs.Add(ns);

            return RedirectToAction("Index");

        }

        //修改

        News ns = new News();

        public ActionResult Edit(int id)

        {

            ns = bs.FindById(id);

            return View(ns);

        }

        //修改

        [HttpPost]

        public ActionResult Edit(News ns)

        {

            bs.Update(ns);

            return RedirectToAction("Index");

        }

        //删除

        public ActionResult Delete(int id)

        {

            bs.Delete(id);

            return RedirectToAction("Index");

        }

    }

}
