为了可以更有效的学习MySQL数据库的操作，下面开始使用wpf来开发MySQL数据库的管理工具，包括数据库的基本操作：增删改查，同时添加其他的功能，深入的理解数据库语句。一边开发一边学习MySQL数据库的操作。
数据库管理工具，命名为DataBaseTools，项目代码托管到github中，前往下载代码。
使用visual studio创建wpf应用程序
直接打开visual studio，笔者使用的vs 2017社区版，免费的，推荐使用社区版，因为其他版本需要收费（虽然有**码，但不推荐）。如图：直接创建wpf应用程序：
创建新项目时会自动创建解决方案，vs的解决方案中可以添加和创建n多个项目，建议创建项目时勾选“新建GIT存储库”，方便后面推送项目至GitHub。创建完成项目后，自动打开项目设计界面，vs右下角有个git工具栏，点击上行箭头进行项目推送，可以选择推送项目至github，只需要登录github账号即可。
创建项目完成后，在解决方案资源管理器中打开mainwindow.xml，打开窗体设计器，如图：
建议在界面代码编辑区，进行手动编写界面代码。
添加简单的基本功能
进行设计简单的界面，罗列几个功能显示区，如图：
该部分界面代码为：

连接MySQL数据库
下面开始来尝试使用C#连接MySQL数据库，首先在当前解决方案中添加一个新的类库项目，这样做的好处是方便进行类库工具话，可以在以后把该项目生成的dll直接引用到其他项目中去。
创建类库项目vcblog_DataHelper，添加nuget程序包：MySQL，右键解决方案资源管理器，添加和管理nuget程序包，搜索MySQL，安装在项目vcblog_DataHelper上。具体项目代码见下节。
执行连接本地数据库后，显示结果如下：
左边已经罗列出了该数据库下的所有表。
