} --------------------编程问答-------------------- 程序中的sql不是你上面图中的那个。程序中的查询没有返回记录。 --------------------编程问答-------------------- 直接下载个记事日历就完成了。
参考 --------------------编程问答-------------------- myTabel.Rows[0][6].ToString(）你这样确定你这个有值? --------------------编程问答-------------------- DataGridViewRow row = datagridview1.Current.Row // 当前行
row.Cells[0] =""
补充：.NET技术 , C#
