Concatenate not outputting file- but no exception?

Aspose.PDF Product Family
1

Aspose.Pdf.dll 7.0.0.0:

On some of our customers’ systems, we occasionally see debug info in our logs suggesting that calls to Concatenate(…) sometimes don’t output anything, but there aren’t any exceptions, either. E.g. our code looks like this:

PdfFileEditor pdfEditor = new PdfFileEditor();

pdfEditor.Concatenate(theLocationMergeFiles, theOutputName);
After the call to Concatenate(…), there should be a file located at theOutputName. But sometimes there isn’t, despite there being no exceptions thrown. We’re unable to reliably reproduce this problem.

Is this a known issue?

Hi Steve,

Please use PdfFileEditor. AllowConcatenateExceptions = true to check if any exception is thrown when concatenation is performed. This will help to understand the issue and identify the cause of the issue. Please see the following code:

PdfFileEditor pdfEditor = new PdfFileEditor();
pdfEditor.AllowConcatenateExceptions = true;
pdfEditor.Concatenate(theLocationMergeFiles, theOutputName);

Please do share your feedback with us.
Sorry for the inconvenience,
