Hi guys,

I'm using PdfSharp in my project - it's cool and fast, that's why I choose it! Thank you!

Would you be kind to help me with next problem:
I use the PdfSharp library to read and process uploaded by user PDF documents. From time to time, there are documents which are cannot be opened by PdfSharp library, but can be easily be opened by any PDF reader (viewer).

I've prepared a small console app, please find it in attachment (InvalidEntryInXrefTable.zip), the userd PdfSharp version is "1.50.4845-RC2a"
It's also contains an example of the PDF document inside.

Looking forward to hearing from you

Thank you

PDFsharp was not built to deal with corrupt PDF files.

Which error message do you get from PDFsharp?

So the file is corrupt. And PDFsharp was not made to fix corrupt files, it was made to modify intact files.
