我正在尝试获取事件触发的单元格的值.
当我尝试强制sender转换为DataGridViewCell:
无法将类型为"System.Windows.Forms.DataGridView"的对象强制转换为"System.Windows.Forms.DataGridViewCell".
你推荐我做什么?
我需要检查值是否小于20,如果是,则将其提高到21.

这可能不是一门精确的科学,但我可以在1GB的数据库中保存多少条记录/表格?我将保存纯文本(意思是:nvarchar,varchar,int,bool)而不是二进制文件/ blob.
对于这个问题,想象一下大约20个表,每个表有9个字段.每个字段都不为空.
