Answer 1

jet.Oledb.4.0不适用于64Bit机器。

您可以将Microsoft.ACE.OLEDB.12.0用于64位系统。您可以检查它是32位还是64位系统。如果32位则使用.JET.OLEDB，否则使用ACE.OLEDB。

Answer 2

您正在使用Jet.OLEDB.4.0驱动程序，该驱动程序在64位系统上运行时出现该错误，最好安装新驱动程序Microsoft Access数据库引擎2010可再发行组件

你还需要从“Provider = Microsoft.Jet.OLEDB.4.0;更改连接字符串; “to”Provider = Microsoft.ACE.OLEDB.12.0;“

我的博客参考：64位版本的'Microsoft.Jet.OLEDB.4.0'Office 2007/2010 Jet驱动程序

希望这会有所帮助。
