我有以下代码:

string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\db\suc.xls; Extended Properties=""Excel 12.0;HDR=YES;""";

// Create Connection to Excel Workbook
using (OleDbConnection connection =
             new OleDbConnection(excelConnectionString))
{
    OleDbCommand command = new OleDbCommand
            ("Select * FROM [Sheet1$]", connection);

    connection.Open();

我收到以下错误:

找不到可安装的ISAM.

在connection.Open().有任何想法吗 ？

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.
