通用权限管理系统组件 (GPM - General Permissions Manager) 中实现系统参数配置保存，附源码...

其实GPM不仅仅是权限管理系统，其实更是一个灵活的轻量级快速.Net开发架构，他需要最短的学习时间，可以最快速入门，并不是通过玩技术来实现我们的日常需求。GPM中只要写一套代码，就可以实现在多种数据库上的稳定运行。

下面我们给大家参考一下如何在GMP中实现系统参数配置的保存功能，开发界面见下图：

数据库中的保存效果如下：

配置文件中的保存效果如下：

实现代码的优点就是，1套代码支持多种数据库，1个参数基本上1行代码就可以实现保存，读取功能，代码的量少稳定性高。见参考代码如下：
