C# NPOI 库和无效的 zip 压缩

Question

I'm using the NPOI library to read and write XLSX spreadsheets in a C# application. This library seems to work, I could open, write and re-open an Excel file.

I found a problem when I tried to open a NPOI file with MS Excel, its say that the file has some corrupted content. However NPOI library can open its file. I could understand that this is a compression issue, seems that the zip compression of xlsx is not valid for Excel and this issue is caused by ICSharpCode.SharpZipLib.dll, for this reason a copy of this dll is distribuited with the NPOI library.

I tried to add this dll in my project references, but the compression still doesn't work. How to solve this issue?

Answer 1

尝试将 DotNetCore.NPOI 与 1.2.0 版一起使用（它对我有用）。
