In my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.

If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?
