由于只注重主要功能实现，并未优化前端页面，所以看起来比较原始。

采用webform技术

三层架构 + webform显示

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="login.aspx.cs" Inherits="login" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<center>
<div>
登录页面<br />
<br />
登录名：<asp:TextBox ID="login_textbox" runat="server"></asp:TextBox>
<br />
<br />
密码：<asp:TextBox ID="password_textbox" runat="server" TextMode="Password"></asp:TextBox>
<br />
<br />
<asp:Button ID="login_button" runat="server" OnClick="login_button_Click" Text="登陆" />
   
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="注册" />
</div>
</center>
</form>
</body>
</html>
