Database2Sharp重要更新之生成Winform框架界面代码

Database2Sharp是一款代码生成工具和数据库文档生成工具,该工具一直伴随着我及我的粉丝们经历过各种各样的项目开发,在实际开发中能带来效率的提高及编程的快乐。不过自上个6.0版本以来,我一直忙于各种项目及研究中,很少继续把新的思想整合进去,最近在做我的Winform开发框架的整理工作,觉得应该改进这段时间来发现的问题,并融入已经逐渐完善的Winform开发框架基础上来,于是经过几天的努力,把该代码生成工具的一些缺陷修复并增加了Winform界面代码生成的功能(以前一直只是生成底层及Web界面层),并重新命名版本号为7.0。以后再继续完善后,在此大版本上再继续升级吧。 

 

本次主要的修改如下:

1)修改设置不重新加载数据库信息。

 

以前版本,为了保证对数据库基础信息的及时更新,只要对一些关键的参数设置,通常都要重新刷新数据库基础信息(如表、列等基础信息),这样生成的代码就会保证使用最新的设置信息。如上图中的过滤表前缀的参数,是为了把表名称转换为友好名称的类名而定义的,他是在数据库加载的时候,自动把表别名信息生成的。

这个问题使用上一直感觉不太好,7.0版本修复了这个问题,把相关的信息保存的同时,在内存中对数据库表、字段等基础对象进行了更新,确保使用最新配置而无需重新加载整个数据库信息。

 

2)Winform界面代码可配置生成

说起Winform界面的代码生成,一般来说就两种界面比较典型,一个是查询列表显示界面,一个是数据查看编辑界面。本功能也主要是提供这两类界面代码的生成,通过配置查询列表中的条件字段以及查询列表字段显示信息,就可以合理生成符合我的WInform框架要求的界面代码,查询列表显示界面类继承自BaseDock基础类。另一方面,通过配置数据查看编辑界面的编辑字段,数据检查字段,判断关键数据重复的字段等参数,可以生成较为完善的数据查看编辑界面代码,生成界面如下所示。

 

以上参数只要执行生成代码一次,即会自动保存起来,下次打开相同表的时候,会把之前的配置信息还原,方便用户的多次操作。由于界面在不同的界面控件(如DevExpress、传统界面等)处理上有所不同,因此生成的界面代码也会根据用户的设置信息进行选择性生成。另外界面代码是我的Winform框架体系里面一部分,所以整合了我的分页控件、基础窗体类的继承等特点,如果你看不懂,可以多看看我的Winform框架文章或者分页控件文章介绍。

Winform界面代码生成后,会直接在代码编辑窗体中打开,用户可以复制或者保存起来放到VS的编辑器中进行相应的修改,后续的工作应该较为轻松了。

 

下面我们来分别看看生成的代码效果如何吧。
