推荐答案

是的；您只需要将连接字符串更改为适合您的数据源的连接字符串即可.

当然，您可以在配置文件中保留许多可用的连接，然后按时间切换.如果您想在此处或在Google上进行搜索，则会有大量的文章.

Yes; you merely need to change the connection string to one that is appropraite for your data source.

Of course, you could keep a number of available connections in a config file and switch as and when. There are articles a-plenty on doing that if you care to search here or on Google.

您只需引用控件的数据源(数据集或数据表)即可.我在检索或制作CRUD命令时也会使用数据源.
像:

You will just have to cite the datasource of your control either a dataset or a datatable. I also use a datasource when im retrieving or making CRUD commands.
like:

...
Dim ds as Dataset
Listbox1.Datasource = ds
...
