Using Aspose.Pdf.Kit for .NET 3.8.0 & Aspose.Pdf.Kit for .NET 3.9.0, Combining the attached pdf files causes the following error.
"Unable to cast object of type 'xeb116a323308e2f7.x0b25947bdf0fba40' to type 'xeb116a323308e2f7.xe3033695b7f6d53d'."
Please advice.
Hi Rakesh,
Thank you very much for considering Aspose.
I have noticed that your PDF files contain PDF Forms, so you can use ConcatenateForms method as shown in the following code snippet:
I have tested the files using above sample and the concatenation was successful.
Aspose.Pdf.Kit.PdfFileEditor editor = new Aspose.Pdf.Kit.PdfFileEditor();
editor.ConcatenateForms(“EGA_Met_Business_Class_Fax_Cover_Sheet.pdf”, “EGA_Authorization_Form.pdf”, “output1.pdf”);
editor.ConcatenateForms(“output1.pdf”, “COMPDISC-ID_LiveCycle_030909.pdf”, “output2.pdf”);
editor.ConcatenateForms(“output2.pdf”, “COMB-89216-HI.pdf”, “output3.pdf”);
If you have any further questions or find some other issue, please do let us know.
Regards,
