篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了数据上报-动态生成winform表单相关的知识，希望对你有一定的参考价值。
winform+Oracle数据库
通过数据库查询出所有列名、数据类型、描述等信息进行动态生成winform表单文件，再通过发射对类进行取值赋值.........适用于表结构单一，需要快速开发的项目
经理预估期1个星期的工作时间，我也不知道如果真的一个星期做完我会不会挂掉，而实际情况是数据库建立都花了一个星期虽然表名称、数据类型都不需要自己想，从建表模型设计，框架寻找。

2.创建一个公用的类CreateModel 由于winform页面需要用到这个类 就直接继承了这个类，而这个类继承了System.Web.UI.Page 可能这样有点不妥 但是对于从来没有这么大工作量的我来说也就简简单单的写了个

例如：aspx页面

来来来 见证一下我们经理的时间预估的能力--所有表，不仅仅只是新增修改列表这些基本的功能，还要像省上上报数据。字段辣么多表那么多用winform开发如果不想点其他的办法，就连页面粘贴复制粘贴复制我都不知道要多久才能完成这个项目
