这可导致自动生成代码以创建将添加到组件托盘中的 ADO.NET 连接、命令和数据适配器对象。
This causes code to be automatically generated to create the ADO.NET connection, command, and data adapter objects that are added to the component tray.
该拖放（drag-and-drop）操作将自动生成所需的 ADO.NET 连接、命令和数据适配器对象，并将其添加到窗体的组件托盘上。
The drag-and-drop operation will automatically generate the required ADO.NET connection, command, and data adapter objects and add them to the form's component tray.
尽管必须使用该方式来实例化适配器对象，但这还是避免了复制数据值。
Although you must instantiate the adapter object with this approach, it still avoids copying the data values.
