Post subject: | Error while merging multiple PDFs |
I am trying to combine multiple PDFs into a single PDF. The PDFs come from SSRS, from some LocalReports that I processed. I am using PDFSharp, because it is already used through out the project. However, the outputDocument.addPage(page) methods throws an InvalidOperationException("Cannot change document.") exception. I have tried many different way of doing this, but I can't get it to work... Here my method, where all the inputs have already been checked: Code: private static void saveFile(string fileName, params byte[][] bytes) { try { PdfDocument outputDocument = new PdfDocument(); for (int i = 0; i < bytes.Length; i++) { using (MemoryStream stream = new MemoryStream(bytes[i])) { PdfDocument inputDocument = PdfReader.Open(stream, PdfDocumentOpenMode.Import); foreach (PdfPage page in inputDocument.Pages) { outputDocument.AddPage(page); //throws the exception !!! } } } outputDocument.Save(fileName); } catch (Exception ex) { throw new Exception("Erreur lors de l'enregistrement du fichier", ex); } } From the examples I saw on the web, this seems to be the right way of doing this... I am opened to other suggestions for merging my PDFs, but I would rather not use another 3rd party lib, like ITextSharp, because PDFSharp is already used in the project. If it matters, I am using VS2010 Pro on a Win7 machine. |
