的原因是行不能以编程方式添加到DataGridView的行集合时，该控件是数据绑定。这是因为结晶水一样清晰​​

The cause is that "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound". It is as clear as crystalline water

解决方案？做的不可以行添加到DataGridView的行集合，将它们添加到底层数据源集合（在您设置到DataGridView的DataSource属性集合）

The solution? Do not add rows to the DataGridView's rows collection, add them to the underlying datasource collection (the collection you are setting in to the DataSource property of the DataGridView)
