三层架构之UI层

之前已经发表了BLL,DAL,MODEL,三个层的源码

继续UI层:

先简单实现用户的登录及注册

高级操作可按照上一篇文章进行源码完善

如图所示↑ UI层目录文件

Reg.aspx 进行注册操作  <数据库的写入和执行>

后台源码如下：

  1 using System;
  2 using System.Collections.Generic;
  3 using System.Linq;
  4 using System.Web;
  5 using System.Web.UI;
  6 using System.Web.UI.WebControls;
  7 using Model;
  8 using BLL;
  9 using DAL;
 10 using System.Windows.Forms;

 12 namespace WebApp
