I have the following code

Dim inputPdf As new PdfDocument

Try

inputPdf = PdfReader.Open(fileName, PdfDocumentOpenMode.Import)
Catch ex As Exception

End Try

I get the exception -

One thing I had notice, the PDF file which is of version 1.4 is working fine, where are PDF file of version 1.5 is not working.

Does any one has any thoughts on how to resolve this?

Thanks

This has nothing to do with the PDF version.

I tried both the files you sent me - and both files are working fine with PDFsharp 1.0.

Please upgrade to PDFsharp 1.0.898 - earlier versions are no longer supported.
