c#web窗体实现对数据库的增删改查，学生管理信息系统~vs2010+access2010

以下是web程序课程后做的期末项目，前端以及页面逻辑结构使用vs搭建，后端服务器采用access数据库连接，仅供参考。欢迎学习交流~Q871501285

解决方案管理器目录结构

下图为项目结构目录，依次创建，css中为网页的层叠样式表，DB文件夹中为数据库文件，四个aspx文件为网站页面。

数据库文件

存放学生基本信息，前端要操作的内容

首页

首页包含功能按钮与查询功能

效果：

功能按钮

查询功能
可查找出数据库的中的数据

首页代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="首页.aspx.cs" Inherits="WebApplication2.WebForm2" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">
