很久不用，再用发现不会连接数据库了，又查了下：

编译过后会在属性窗口出现可以设置的属性

SourceTable属性默认为空， 点击右侧的那个三个点按钮，会弹出对话框

点击Data Source右侧的那个两个点按钮

点Add按钮新增一个数据库连接

输入Name，Provider Type选择SqlSchemaProvider,点击Connection String 右侧的三点按钮

输入Server Name,可以选择Windows身份认证或者SQL Server 密码认证，然后选择一个数据库，最后点击OK，接着再点OK，回到选择表界面，下拉框中选择刚加入的数据库，会自动列出该库中的所有表

2、设置SourceTable
先执行
Tools-Build
然后在属性杂项一栏中设置SourceTable
选择数据库，再选择表。
