LoadFromFile - System.NullReferenceException

[zahnonen]

Hello,
when I try to load a workbook file.xls with LoadFromFile, I get a System.NullReferenceException.
If I save this file.xls as file.xlsx in the same folder, it doesn't happen.
Open mode 97/2003 has no effect on the exception.

What can I do

Hello,

Thank for your inquiry.
I used the latest version of Spire.XLS (Spire.XLS Pack Version: 11.6) to test your file, but did not reproduce your problem. If you were not using the latest version, we recommend you give it a try. If the problem still exists, please provide your test environment such as OS info (E.g. Windows7, 64bit) and region setting (E.g. China, Chinese), your application type such as Console app (.NET Framework 4.5) for our investigation. Thanks in advance.

Sincerely,
Annika

Hello Annika,

unfortunately I get the same result (see pictures). What can the fault be?

Best regards, Zahnonen

OK, I have not used V11.6, with V11.6 it's fine, thanks!

Best regards, Zahnonen
