Error merging previously merged pdf with new files

[KShubert]

Hello,

I am merging multiple documents into a pdf using Spire and part of our requirement is that we can use this merged pdf and merge it with other pdfs, but if excel information is present in a merged pdf when attempting to merge it again I am receiving this error:
at Spire.Pdf.PdfPageBase.get_CropBox()
at Spire.Pdf.Widget.PdfPageCollection.Add(PdfDocumentBase A_0, PdfPageBase A_1, List`1 A_2)
at Spire.Pdf.PdfNewDocument.ClonePage(PdfDocumentBase ldDoc, PdfPageBase page, List`1 destinations)
at Spire.Pdf.PdfDocumentBase.ImportPageRange(PdfDocumentBase ldDoc, Int32 startIndex, Int32 endIndex)
at Spire.Pdf.PdfDocumentBase.ᜋ(PdfDocumentBase A_0)
at Spire.Pdf.PdfDocumentBase.ᜀ(Stream[] A_0)
at Spire.Pdf.PdfDocument.MergeFiles(Stream[] streams)

This is an essential part of our process and would appreciate any help in resolving this issue.

I have attached an example Excel document and a merged pdf with excel information present to help with any merging testing.

Hi,

Thanks for your inquiry.
How do you merge your PDF files into one PDF file? In your attachment, there is only one PDF. I used following code to merge your PDF file, there is no error. Everything worked fine.

Code: Select all

            string path1 = path + @"MergedWordandExcel.pdf";
            string path2 = path + @"MergedWordandExcel.pdf";
            string output = "19466.pdf";
            //use your original file twice
            PdfDocumentBase doc = PdfDocument.MergeFiles(path1, path2);
            doc.Save(output);

Hello,

I should have specified I am merging a list of files from a MemoryStream.

Code: Select all

//mergeList is a list of PDFs in MemoryStreams
PdfDocumentBase result = PdfDocument.MergeFiles(mergeList.ToArray());
                    result.Save(masterPDFFile, Spire.Pdf.FileFormat.PDF);


Edit:
I have done some more testing with a much simpler test.

Code: Select all

PdfDocumentBase result = PdfDocument.MergeFiles(Directory.GetFiles(folderPath));
            result.Save(folderPath + "\\New-Merged.pdf", Spire.Pdf.FileFormat.PDF);


With the attached pdfs in the LocalTest Folder it will work the first time but if I attempt to merge again (changing the output name aswell) it is failing.

I have resolved my issue by updating to the most recent HotFix for Spire.Pdf (5.11.0)
