namespace BBS.Models
{
using System;
using System.Collections.Generic;
public partial class art_CategoryInfo
{
public int Category_ID { get; set; }
public string Category_title { get; set; }
public string Category_description { get; set; }
public string category_img { get; set; }
public int Enabeld { get; set; }
}
}
然后是连接实体的DbContext (DB.cs)
using System;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using BBS.Models;
public partial class connetionEntities : DbContext
{
public connetionEntities()
: base("name=Entities")
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
throw new UnintentionalCodeFirstException();
}
public DbSet art_CategoryInfo { get; set; }
}
然后是IRespoistory 的接口层(IRespoistory .cs)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
using System.Web;
namespace BBS.Models
{
public interface IRepository
{
TEntity GetById(int id);
IEnumerable SearchFor(Expression> predicate);
IEnumerable GetAll();
void Edit(TEntity entity);
void Insert(TEntity entity);
void Delete(TEntity entity);
}
}
然后是Respoistory层（Respoistory.cs）
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using BBS.Models;
using System.Linq.Expressions;
using System.Data.Entity;
using System.Data;
namespace BBS.Models
{
public class Respoistory : IRepository where TEntity:class
{
protected DbSet DbSet;
private readonly DbContext _dbContext;
public Respoistory(DbContext dbcontext)
{
_dbContext = dbcontext;
DbSet = _dbContext.Set();
}
public Respoistory()
{
}
public TEntity GetById(int id)
{
return DbSet.Find(id);
}
public IEnumerable SearchFor(Expression> predicate)
{
return DbSet.Where(predicate);
}
public IEnumerable GetAll()
{
return DbSet;
}
public void Edit(TEntity entity)
{
_dbContext.Entry(entity).State = EntityState.Modified;
_dbContext.SaveChanges();
}
public void Insert(TEntity entity)
{
DbSet.Add(entity);
_dbContext.SaveChanges();
}
public void Delete(TEntity entity)
{
DbSet.Remove(entity);
_dbContext.SaveChanges();
}
}
}
最后是Controller 层如何调用了
这里我写了简单的实列
HomeConcoller.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using BBS.Models;
namespace BBS.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
Respoistory Res_ArtCate = new Respoistory(new connetionEntities());
public ActionResult Index()
{
return View(Res_ArtCate.GetAll());
}
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(art_CategoryInfo art)
{
if (ModelState.IsValid)
{
Res_ArtCate.Insert(art);
return RedirectToAction("Index");
}
return View(art);
}
public ActionResult Edit(int id)
{
art_CategoryInfo arts = Res_ArtCate.GetById(id);
if (arts == null)
{
return HttpNotFound();
}
return View(arts);
}
[HttpPost]
public ActionResult Edit(art_CategoryInfo art)
{
if (ModelState.IsValid)
{
Res_ArtCate.Edit(art);
return RedirectToAction("Index");
}
return View(art);
}
public ActionResult Delete(int id)
{
art_CategoryInfo art = Res_ArtCate.GetById(id);
if (art == null)
{
return HttpNotFound();
}
return View(art);
}
[HttpPost,ActionName("Delete")]
public ActionResult DeleteConfirmed(int id)
{
art_CategoryInfo art = Res_ArtCate.GetById(id);
Res_ArtCate.Delete(art);
return RedirectToAction("Index");
}
}
}
以上就是一个简单的EF Respoistry（仓库）了
