system.nullReference Exception when merging documents

[jperkinsSC]

Hi Support,
We are using latest version of spire.pdf.dll and spire.pdf.wpf.dll and we are getting system.nullReference Exception when we merge the splitted documents.
steps we are using are
1. Split the pdf document using following code.

Code: Select all

string pattern = Path.Combine(outputPath, Path.GetFileNameWithoutExtension(doc) + "_{0}.pdf");
                   Doc.Split(pattern, 1);

2. Merging the same splitted documents using following code.

Code: Select all

var doc2 = PdfDocument.MergeFiles(Directory.GetFiles(outputPath));
           doc2.Save(outputFile, FileFormat.PDF);

I have send you an e-mail containing the original document in which we are facing this specific issue.

I did notice that there is an error in the second splitted result, this caused the exception when merging. I already logged it into our bug tracking system for fixing, if there is any update, I will let you know immediately. Sorry for the inconvenience caused.
