偶做的用户管理系统


答案：偶做的用户管理系统
因为代码比较多,只贴一下,添加用户的代码,我把表示层和业务逻辑层分开了,单独建立了一个Cls_user的类来对用户集中进行管理,里面包括了对用户的添加,删除,修改的方法,以及访问用户的名称,密码,权限等的字段,这样分开做也符合多层架构的原则,我没有单独做dal层,因为我部打算以后换数据库.
在前台的窗体中有几个下拉列表控件,我是分别用散列表和DataTable来做数据动态绑定的,也算是一个小技巧吧.
在业务逻辑的类里我用使用了方法的输出参数,大家可以顺便看一下输出参数怎么用.

先贴前台的显示代码?注意dropdownlist控件的DataTextField和DataValueField属性
