如何使用C＃访问Excel工作表中的公式？

Question

I am parsing thorugh a 2000+ record excel file, and need ot be able to grab the formula itself from the cells and not just the value. For example, one cell 'Contributions' may be a single number like 1500 or it can be a few numbers 1500+500-200 but I dont want the total, I want the actual formula so I can get the different numbers.

I was just parsing with an oledbconnection and that only seems to get me the total. How would I go about getting the formula? Is it possible (I can get it in either XLS or XLSX)?

Thank you.

Using OLE Automation, you can access the formula in a cell as follows:

formula = worksheet.Cells(1, 1).Formula

EDIT:

To use OLE Automation in your C# project, see the following Microsoft KB article :

The xslx is an xml file so it should be easy enough to read. Alternatively you can use third-part components like the one from Infragistics that allows you to read xsl-files programmatically and also to access the formulas.
