Combine two or more PDF s

Question

Background  I need to provide a weekly report package for my sales staff  This package contains several  5-10  crystal reports   Problem  I would like to allow a user to run all reports and also just run a single report  I was thinking I could do this by creating the reports and then doing   List lt ReportClass gt  reports   new List lt ReportClass gt     reports Add new WeeklyReport1     reports Add new WeeklyReport2     reports Add new WeeklyReport3      lt snip gt   foreach  ReportClass report in reports        report ExportToDisk ExportFormatType PortableDocFormat    c  reports     report ResourceName     pdf        This would provide me a folder full of the reports  but I would like to email everyone a single PDF with all the weekly reports  So I need to combine them   Is there an easy way to do this without install any more third party controls  I already have DevExpress  amp  CrystalReports and I d prefer not to add too many more   Would it be best to combine them in the foreach loop or in a seperate loop   or an alternate way

This is something that I figured out  and wanted to share with you  using PdfSharp  Here you can join multiple Pdfs in one  without the need of an output directory  following the input list order      public static byte   MergePdf List lt byte   gt  pdfs                List lt PdfSharp Pdf PdfDocument gt  lstDocuments   new List lt PdfSharp Pdf PdfDocument gt             foreach  var pdf in pdfs                        lstDocuments Add PdfReader Open new MemoryStream pdf   PdfDocumentOpenMode Import                       using  PdfSharp Pdf PdfDocument outPdf   new PdfSharp Pdf PdfDocument                           for int i   1  i lt   lstDocuments Count  i                                  foreach PdfSharp Pdf PdfPage page in lstDocuments i-1  Pages                                        outPdf AddPage page                                                MemoryStream stream   new MemoryStream                outPdf Save stream  false               byte   bytes   stream ToArray                 return bytes

I know a lot of people have recommended PDF Sharp  however it doesn t look like that project has been updated since june of 2008   Further  source isn t available   Personally  I ve been playing with iTextSharp which has been pretty easy to work with

To solve a similar problem i used iTextSharp like this     Create the document which will contain the combined PDF s Document document   new Document       Create a writer for de document PdfCopy writer   new PdfCopy document  new FileStream OutPutFilePath  FileMode Create    if  writer    null         return       Open the document document Open       Get the files you want to combine string   filePaths   Directory GetFiles DirectoryPathWhereYouHaveYourFiles   foreach  string filePath in filePaths           Read the PDF file      using  PdfReader reader   new PdfReader vls FilePath                     Add the file to the combined one          writer AddDocument reader               Finally close the document and writer writer Close    document Close

PDFsharp seems to allow merging multiple PDF documents into one   And the same is also possible with ITextSharp

There s some good answers here already  but I thought I might mention that pdftk might be useful for this task  Instead of producing one PDF directly  you could produce each PDF you need and then combine them together as a post-process with pdftk   This could even be done from within your program using a system   or ShellExecute   call

I had to solve a similar problem and what I ended up doing was creating a small pdfmerge utility that uses the PDFSharp project which is essentially MIT licensed   The code is dead simple  I needed a cmdline utility so I have more code dedicated to parsing the arguments than I do for the PDF merging   using  PdfDocument one   PdfReader Open  file1 pdf   PdfDocumentOpenMode Import   using  PdfDocument two   PdfReader Open  file2 pdf   PdfDocumentOpenMode Import   using  PdfDocument outPdf   new PdfDocument                          CopyPages one  outPdf       CopyPages two  outPdf        outPdf Save  file1and2 pdf       void CopyPages PdfDocument from  PdfDocument to        for  int i   0  i  lt  from PageCount  i                  to AddPage from Pages i
