Vidual Studio 2017 C＃System.Data.OleDb无法读取较新的Excel文件

Question

我使用Visual Studio Professional 2017（15.9.16和.NET Framework 4.7.02558），以C＃编码。

我拥有使用System.Data.OleDB的现有代码，该代码可以成功读取较旧的Excel文件，但是较新的Excel文件却无法读取，并收到错误消息“外部表未采用预期的格式”。完整的例外情况显示在这篇文章的末尾。

我声称这是一个版本问题，因为如果我将文件下转换为Excel 2003，则读取工作簿成功。唯一的区别是Excel文件的版本。

我做了一些初步的尝试，希望发现我只需要升级Visual Studio中的某些组件，但是在这方面我还没有走运；这个难题有很多片段，我不知道从哪里开始。

好的，我遇到了正确的解决方案。而不是OleDb，我应该使用OpenXML（DocumentFormat.OpenXML）。我现在正在逐步了解这种方法
