Compilation : can't find "namespace"

I try to use a C# script to extract text from PDF (yeah again, my python script works but not in OB2 but outside, it’s not convenient, I would like to manage everything from OB2).

Here the script : Parsing PDF Files using iTextSharp (C#, .NET) | Square PDF .NET

It uses [iTextSharp](iText® 5 .NET, a .NET PDF library download |

I downloaded the NUGET file, unzipped it, and copied/pasted itextsharp.dll to OB2 exe file’s directory.

Here the code :



  value = "Factures\\20200926004520200GNXXSDCFAEAU00027920\\20191108225218000ARCHSCCFAEAU06819713.pdf"

  => VAR @path


public static string ExtractTextFromPdf(string path)


  using (PdfReader reader = new PdfReader(path))


    StringBuilder text = new StringBuilder();

    for (int i = 1; i <= reader.NumberOfPages; i++)


        text.Append(PdfTextExtractor.GetTextFromPage(reader, i));


    return text.ToString();



string pdftext = ExtractTextFromPdf(path);

I typed this in the “namespace” fields :

using itextsharp.text.pdf;
using itextsharp.text.pdf.parser;

(I deleted uppercases because DLL’s name has no ones, but even keeping them it still not works !)

And I got this error :

[IDLE] CompilationErrorException: error CS0246: The type or namespace name 'using itextsharp' could not be found (are you missing a using directive or an assembly reference?)

Ok, I did what it said here : Importing .DLL Files into OB2 to use with Lolicode / C#

DLL appears in the plugin list, but I got the same error

You don’t type using in the namespace. You just type the name

As Pure said, only type


in the usings box
