I have added a simple 'concatenate files' operation to an application, based on the code in the pdfsharp samples. Code appears to be working fine for many pdf docs.

However when attempting to open some dpf files [using PdfReader.Open(file, PdfDocumentOpenMode.Import)] a PdfSharp.Pdf.IO.PdfReaderException is thrown by the pdfsharp code.

Acrobat reader 8 opens the files without any problems.

As a test I copied some of the problem pdf files to the folder used by the concatenate documents pdfsharp sample & ran the sample. It stopped with the same exception. The error & stac trace from the sample app are included below. I did not change the saple source.k

Does anyone know about this error?
can anyone give me some clues as to how to go about fixing it?
I am new to pdf files, but am happy to work on a fix for the library (if required).

Thanks in advance

Hi,

the UNEXPECTED ERROR while formatting message... comes because a satellite assembly with the errors messages was not found. This may be a build error.

The actual error is in PdfSharp.Pdf.IO.Parser.ReadSymbol called from PdfSharp.Pdf.IO.Parser.ReadTrailer. I cannot guess what happens here. Please send me the PDF (using the e-mail address published in the source code) and I will take a look at it.

Hi Stefan,

Did you ever get to the bottom of this problem? I am getting the same error.
