PdfSharp.Pdf.IO.PdfReaderException: 'Unexpected token 'True' in PDF stream. The file may be corrupted. If you think this is a bug in PDFsharp, please send us your PDF file.'

Read all the pdf and converted to bytes. Stored in List<byte[]>. From this list, take first 25 items and try to create pdf getting "PdfSharp.Pdf.IO.PdfReaderException". This is working with "2020_f1095c.pdf", but not working with "2021_f1095c.pdf". The file "2021_f1095c.pdf" downloaded from https://www.irs.gov/pub/irs-pdf/f1095c.pdf

I have attached demo visual studio console application project to re-produce the issue.

We are working on Dec-2021 year end release. It will be helpful if you provide solution.

I am waiting for the solution. Is there any fix?

Is this because of corrupted .PDF file or other issues?

Hi!

I downloaded the file and it opens successfully.

Code:
PdfDocument inputDocument1 = PdfReader.Open(@"C:\Users\...\f1095c.pdf", PdfDocumentOpenMode.Import);
var x = inputDocument1.Pages.Count;


Sorry, but I did not want to download those 7z files and and try to find out how to combine them.
You lost me with this sentence: "Read all the pdf and converted to bytes. Stored in List<byte[]>. From this list, take first 25 items and try to create pdf getting "PdfSharp.Pdf.IO.PdfReaderException"."


Are you using the latest NuGet version? Which exactly?
Is it 1.51.5186-beta?

No. Using 1.50.5147.0 stable version.

Please refer below C# method. First create bytes from PDFDcoument. Then using PdfDocument getting error "PdfSharp.Pdf.IO.PdfReaderException: 'Unexpected token 'True' in PDF stream. The file may be corrupted. If you think this is a bug in PDFsharp, please send us your PDF file.'"


Code:
byte[] pdfBytes = null;

            var document = PdfReader.Open(filePath);
            using (var stream = new MemoryStream())
            {
                document.Save(stream);
                pdfBytes = stream.ToArray();
            }

            using (var outputDocument = new PdfDocument())
            {
                using (var mem = new MemoryStream(pdfBytes))
                {
                    using (var pdfToMerge = PdfReader.Open(mem, PdfDocumentOpenMode.Import))
                    {
                    }
                }
            }

Does the error also occur with 1.51.5186-beta?

Yes. I don't have time to step through the code.
Consider taking the PDFsharp source code and incorporate some of the proposed pull requests.

Thanks for the response.

This year end we needs to give release for year end changes. The functionality which is breaking now is important for this release.
It could be helpful for us, if we get solution before Dec 1st week end.

Waiting for your support to come out of this issue.

The bug in PDFsharp has been fixed with recent builds of PDFsharp 6.0.0.

The PdfSharp.dll 6.0.0 required min .net framework 6.0. But our project uses 4.6.1.

Can you let me know, is there any option to get PdfSharp.dll to support .net framework 4.6.1 with the 'Unexpected token True' issue fix?
