winform之学生管理项目

我还是要做一个简易的学生管理系统,使用winform的控件来完成页面的搭建,c sharp完成逻辑的填充,使用mysql来存储数据。

登录这里的最主要的逻辑就是点击登录按钮后连接数据库进行判断然后登录到主页面。其次是当用户输入完成用户名之后会自动寻找匹配的图片并显示出来。

注册这里就是简单的添加一下,然后给密码、身份证、手机号加一个判断格式的正则,顺便在加入数据库的时候计算出年龄、性别、出生年月。

重置密码这里也是差不多的逻辑。

显示主页面只有一些基础的功能,用listView来显示数据库的数据。

修改这里我设置只能修改用户自己的各项信息。

这里我先写了登录页面的一部分代码。
