推荐答案

这是一个非常基本且自我解释的错误。如果您正在复制和粘贴代码而不试图理解它的作用，那么您自己就是一种伤害。一个简单的谷歌搜索，你可能有更多的可能自己解决这个错误，这也可以帮助你了解自己解决问题的重要性。



鉴于我对您的项目一无所知，也没有提供大量的代码片段，我只能假设您正在使用数据网格视图。



如果您参考这个链接



DataGridView.DataSource属性（System.Windows.Forms） [ ^ ]



那里是一个代码片段，向您展示如何声明数据网格视图，这是您遇到的错误。

This is a pretty basic and self explanatory error. If you are copying and pasting code without attempting to understand what it does you are doing yourself a disservice. A simple google search and you would have more than likely resolved this error on your own which would have also helped you learn how important figuring things out on your own is.

Given I don't know anything about your project nor did you provide much of a code snippet I can only assume you are using a data grid view.

If you reference this link

DataGridView.DataSource Property (System.Windows.Forms)[^]

There is a code snippet that shows you how to declare a data grid view which is what the error you are running into.
