找不到可安装的ISAM

Question

我正在使用vb.net 2003,我想使用OleDb Connection读取excel文件2003.但是当我将IMEX=1属性放在连接字符串上时,我遇到了问题.但是当我必须退出这个IMEX属性时,系统运行没有错误.这是我的连接字符串

xlsCon = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & pathName & " ; Extended Properties=Excel 8.0;IMEX=1")

任何人都可以帮助我如何修复此错误？我需要放置IMEX属性,以便它告诉驱动程序始终读取每个单元格上的混合(字符串,整数,日期)数据类型.

这是我遇到的错误.

如果使用多于1个扩展属性,则必须引用值标记,否则驱动程序无法将它们与连接字符串中的其他非扩展属性区分开来;

... pathName & ";Extended Properties=""Excel 8.0;IMEX=1"""
