C# 使用Excel 2013打开.xls（97-2003）文件后，使用ACE读取这些文件

很长一段时间以来，我们一直在使用Access Database Engine 2010 V.14.0.4763.1000从c.Net framework 4.0中读取Excel 97-2003.xls文件，并取得了成功的结果。但现在，在使用Excel 2013打开文件并以97-2003.xls格式再次保存后，我们无法再读取这些文件

它给出了以下错误：

外部表不是预期的格式

当我们使用Excel 2007或2010打开和保存文件时，不会发生这种情况，只有在使用2013时才会发生。我们使用以下连接字符串读取文件：

Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=Excel 8.0;HDR=YES

其中{0}被文件名和路径替换。Excel 2013似乎以ACE不了解的方式破坏了97-2003文件结构。我们有办法解决这个问题吗

需要明确的是，我们需要读取的文件格式始终是.xls 97-2003，我们不想读取.xlsx文件。我们可以毫无问题地执行此操作，但为了与其他系统兼容，我们需要使用97-2003

编辑：

我做了一个非常简单的测试程序来说明，你可以在这里得到它：

.rar文件包含：

ExcelReadingTest.exe将启动该程序 Program.cs源代码 SavedFromExcel2007.xls以97-2003格式从Excel 2007保存的Excel文件示例 SavedFromExcel2013.xls以97-2003格式从Excel 2013保存的相同Excel文件 要运行示例，请在c:\temp中保存所有文件并在cmd控制台上键入：

C:\>cd c:\temp (Enter)
C:\temp>ExcelReadingTest SavedFromExcel2007.xls (Enter)

您将获得：

1       Hello
2       World
3       Reading
4       Excel
Press Enter...

如果您键入：

C:\temp>ExcelReadingTest SavedFromExcel2013.xls (Enter)

安装Access Database Engine 2007 12.0.6612.1000后，您将获得：
