Unable to find object at PDF cross-reference stream location. (abcpdf)

I am getting below error when processing the single page pdf.

May i know why i am getting this error

Doc theSrc = new Doc(); theSrc.Read(e.FullPath); on this line

Unable to find object at PDF cross-reference stream location.

Thanks,

If you use ABCpdf's ExtraChecks feature that would give you the option to either try and get ABCpdf to fix the corruption, or have your own application/site issue a warning that the PDF is corrupt.

Of course there are limits to what ABCpdf can fix - in that case you would still end receiving an error from ABCpdf.

In terms of code, the logic would be something like this:

                try
                {
                    doc.Read(inFile);
                    // No corruption detected
                    doc.Save("good.pdf");
                }
                catch
                {
                    try
                    {
                        doc.Read(inFile, new XReadOptions { ExtraChecks = true });
                        // ExtraChecks managed to fix the corruption
                        doc.Save("fixed.pdf"));
                    }
                    catch
                    {
                        // ABCpdf could not fix the corruption
                    }
                }
