I'm using the NPOI library to read a .xlsx document and convert to dataSet. When I try to instantiate the class XSSFWorkbook, I get an error.

My code:

Dim file As New FileStream(myFile, FileMode.Open, FileAccess.Read)
Dim oDs As New List(Of entity.myFile)
Dim libro As New XSSFWorkbook(file)

I obtain the following error:

Unable to load the file or assembly  'ICSharpCode.SharpZipLib,
Version=0.86.0.518, Culture=neutral, PublicKeyToken=1b03e6acf1164f73'
or one of its dependencies. The system can not find the specified
file.

what's wrong here?

Which version of NPOI are you using? You may need to update NPOI to fix this issue. See the bug fixes in release notes of [version 2.4.0](https://www.nuget.org/packages/NPOI/2.4.0). – krlzlx Feb 07 '19 at 15:40
