how to select rows from excel sheet in c#

Question

Hi I have written a code to read from excel sheets and query them according to filter set But am stuck at

Select * from [sheetname] where [col] not like '%something%'

How can I write the not part? Rest all query just work fine The one above ignores the not and executes

Answer 1

If you don't have to use ADO and OLE to read your spreadsheet, I would recommend using EP Plus . It's a project that allows you to work with Spreadsheets in a much better OOP paradigm. It also abstracts all of the gotchas that come from the different internal formatting of .xlsx files versus the older .xls files.

Answer 2

Is it just you don't have quotes around %something% ?
