vb web应用程序中的电子表格连接

Question

我的客户希望在他们的网站上获得他们的价目表。我试图使用电子表格（.xlsx）作为数据源，以便在数据出现在网站上之前限制数据的处理。

该网站在IIS 7上运行。服务器是Windows Server 2008.我已将.NET Framework更新到4.0。

它没有安装任何Office软件包，我的预感是我的问题所在，但我真的很想确定。

继承人的错误文本我越来越：

对于XLSX文件，您需要像这样修改连接字符串。

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES";
