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：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;
 using System.Web.UI;
 using System.Web.UI.WebControls;
 using Model;
 using BLL;
 using DAL;
 using System.Windows.Forms;

 namespace WebApp
 {
     public partial class Reg : System.Web.UI.Page
     {
         User_Table user_Table;
         LoginManger lm = new LoginManger(); //实例化登录验证类
         AEScook aScook = new AEScook();  //实例化AES加密类
         protected void Page_Load(object sender, EventArgs e)
         {
 　　　　　　　　//自动执行
         }
         protected void btn_Reg_Click(object sender, EventArgs e)
         {
