我试图创建一个用户提交个人信息并将数据保存在Access数据库中的小应用程序。连接到ASP.Net中的自定义数据库
返回的错误没有任何意义,因为我试图将正确数量的值插入表中。
这些值是第一个,最后一个,年龄和性别。
这是我的代码,然后按我提交按钮时得到的错误。
感谢您的帮助。

谢谢,但这不起作用 – Geo 2012-03-03 06:28:22
您的访问表中可能有一些需要插入值的列。他们中的任何一个是否设置为非空?还是有一个主键需要一个值?您在上面提到了“ID”字段,但主键不会插入默认值,除非您已将其设置为“自动编号”列。 – Bauhaus 2012-03-03 06:37:40
ID正在搞乱我的INSERT。感谢您的帮助 – Geo 2012-03-05 00:51:32
