'The file is corrupt and cannot be opened' OpenXML

问题

I got that code from OpenXML sdk and instead of SpreadsheetDocument.Create, I used SpreadsheetDocument.Open

This code is working and add an image in .xlsx, after image added to the file. I open the file which shows ->

The file is corrupt and cannot be opened

If you want more details Please! let me know.

Thanks for the help!

回答1:

Not sure how many workbookparts and worksheetparts a xlsx file can handle and if the SheetId must be document unique for all Sheets. Try changing the Id to e.g. 5 if that does not help: do not create a new workbookpart for the sheet, use existig one, if possible.

回答2:

The file is corrupt and cannot be opened

Uncheck all the options under Protected View and confirm by pressing OK.

Restart Excel and try to open the broken Excel documents.

If that doesn't work, typically when you create XSLX files and there is an error, you see this:

Can you check your Temporary Internet Files for the log. The log file should have info on what is malformed. Please update your question with any additional info.
