本文讨论了DataGridView控件在允许用户添加行时可能出现的NullReferenceException异常问题。建议在不需要用户添加行的情况下，设置DataGridView的AllowUserToAddRows属性为False，以避免获取空值引发的异常。

If you set the datagridview.allowuseraddrows = true, then there will be a row with value null, and then when you traversal the rows of the datagridview.rows[X].cells[Y].value, there will be a exception, nullreferenceexception.

Keep in mind that, if you don't want the user to add row, set the allowuseraddrows to false, then the datagridview will be more safe, either when you get the value or other operators.
