Hello!
I am using PDFsharp library of version 1.50.5147.0.
When i try import some PDF document in the class PdfSharp.Pdf.PdfDocument:
PdfDocument inputDocument = PdfReader.Open("920.pdf", PdfDocumentOpenMode.Import);
error occurs:
Unexpected character '0xffff' in PDF stream. The file may be corrupted. If you think this is a bug in PDFsharp, please send us your PDF file.

I am having a similar issue when I try to load existing PDFs to merge I get unexpected character 0xfff in PDF stream. However I can open the documents in Adobe reader and I have also merge these document successfully with other merge tools. Looking at the forum it appears I'm not alone in experiencing this difficulty I'm hoping that someone has a resolution.

unfortunately, the forum doesn't allow me to upload the PDF which is an issue.

Any assistance would be greatly received

Regards



John

Small PDFs can be uploaded as ZIP files.

Most likely a corrupt PDF file.
