PDFsharp & MigraDoc Forum

I have a pdf where an object ist finished with "endobject" instead of "endobj".

Example PDF Part:

8 0 obj
<< /Length 3910
/Subtype /XML
/Type /Metadata
>>
stream
...
endstream
endobject

Than the following exception is raised:

PdfSharp.Pdf.IO.PdfReaderException
HResult=0x80131500
Message=Token 'endobject' was not expected.
Source=PdfSharp-wpf
StackTrace:
at PdfSharp.Internal.ParserDiagnostics.ThrowParserException(String message)
at PdfSharp.Pdf.IO.Parser.ReadObjectInternal(PdfObject pdfObject, PdfObjectID objectID, Boolean includeReferences, Boolean fromObjectStream, SuppressExceptions suppressObjectOrderExceptions)
at PdfSharp.Pdf.IO.Parser.ReadIndirectObject(PdfReference pdfReference, SuppressExceptions suppressObjectOrderExceptions, Boolean withoutDecrypting)
at PdfSharp.Pdf.IO.Parser.ReadAllIndirectObjects()
at PdfSharp.Pdf.IO.PdfReader.OpenFromStream(Stream stream, String password, PdfDocumentOpenMode openMode, PdfPasswordProvider passwordProvider, PdfReaderOptions options)
at PdfSharp.Pdf.IO.PdfReader.Open(Stream stream, PdfDocumentOpenMode openMode, PdfReaderOptions options)

Other Tools, like Acrobat Reader oder PdfPig opens the PDF without error.
Is there a fix for this problem?

"endobj" is correct according to PDF specs and "endobject" is not correct.

Where does the "endobject" in the PDF come from? Was it edited manually? Was it created by a widespread software?
Is it worth changing PDFsharp to support this anomaly in PDF files?
Will Adobe Reader fix the PDF when you use "File => Save as" to save the PDF again?

The PDF comes from Producer "ReportsAnywhere".
Yes, Acrobat Reader fixes the PDF.

I could not find that product or company doing a quick Internet and AI search.
Do you have further information?

Maybe "endobject" was the work of a different producer.
Since there was only 1 reported case and we do not even have a PDF yet, I see no point in adapting PDFsharp for that anomaly.

Here ist the "Creation Entry" from the pdf:
<< /CreationDate (D:20251006114013) /Creator (ReportsAnywhere http://www.reportsanywhere.com) /Producer (ReportsAnywherev6.0.83) /Title (RGTPAUNTENZF) >>

And here ist the object with the "endobject"-Tag as end:
8 0 obj
<< /Length 3910
/Subtype /XML
/Type /Metadata
>>

Thanks for the feedback.

it would be good to have the PDF file for analysis and, if we decide to support it, for testing.

The URL is for sale. Do you have any other information about the company?
