抽像类：
复制代码 代码如下:
public abstract class AbUserAll
{
public abstract IQueryable<User_ALL> FindUserAll();
public abstract User_ALL FindUserAllById(int userid);
public abstract void Add(User_ALL user);
public abstract void Update(User_ALL user);
public abstract void Delete(User_ALL user);
public abstract void Save();
}
复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace WF.Models.DAL
{
public class UserDal:IDAL.AbUserAll
{
private PL_ModelDataContext db = new PL_ModelDataContext();
public override IQueryable<User_ALL> FindUserAll()
{
return db.User_ALL;
}
public override void Delete(User_ALL user)
{
db.User_ALL.DeleteOnSubmit(user);
}
public override void Save()
{
db.SubmitChanges();
}
public override User_ALL FindUserAllById(int userid)
{
return db.User_ALL.SingleOrDefault(o => o.INT == userid);
}
public override void Add(User_ALL user)
{
db.User_ALL.InsertOnSubmit(user);
}
public override void Update(User_ALL user)
{
var editStudent = db.User_ALL.SingleOrDefault<User_ALL>(s => s.INT == user.INT);
if (editStudent != null)
{
editStudent.UserName = user.UserName;
editStudent.Address = user.Address;
}
db.SubmitChanges();
}
}
}
复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace WF.Controllers
{
public class UserController : Controller
{
Models.DAL.UserDal dbuser = new Models.DAL.UserDal();
//
// GET: /User/
