Hi, it's enum.net issue,i have post it to its github site. but now i have another issue, how to open an password protected excel for reading? Is it possible for the 2.7 version?

code:

fs = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read); WorkbookFactory.Create(fs, true);

exception: “RemoveDataValidation” has not been implemented

Password protection is only available for xlsx files:

IWorkbook workbook = WorkbookFactory.Create("encryped.xlsx", "password");

I you don't know the password, you can't open such file.

don't know password

This is illegal. We don't provide this kind of feature.

@softboy99 I checked Enums.NET nuget just now. The last version is just released 3 month ago. Why do you say it's not maintained anymore? Any clues?

Only one question in one issue. If you have other question, please open a new issue. Thanks

Can you create a single console project and reproduce the issue? I'm afraid the issue you are encountering is somewhat related to your package reference in your project.

According to the call stack, this issue is caused by AsSpan method. It's nothing to do with Enums.NET.
