string fileName1 = FolderName + "Sample1.pdf";
string fileName2 = FolderName + "Sample2.pdf";
string fileNameMerged = FolderName + "Merged.pdf";
REDocument doc1 = REFile.OpenDocumentFile(fileName1, new PDFDecoder());//use PDFDecoder open one pdf file
REDocument doc2 = REFile.OpenDocumentFile(fileName2, new PDFDecoder());//use PDFDecoder open another pdf file
BaseDocument docMerged = doc1.MergeDocument(doc2);//merge two pdf
REFile.SaveDocumentFile((REDocument)docMerged, fileNameMerged, new PDFEncoder());//save new pdf
C#.NET PDF Document Merging FAQs
Q: I am looking for an advanced PDF document merging library which can help me finish following task. I need to select a group of PDF pages from each of the target PDF documents and combine all those selected PDF document pages into a new PDF document file. Can RasterEdge PDF document merging library control meet my request?
A: Sorry, now our C#.NET PDF document merging library assembly can only support merging two PDF document files in following two situations. One is to add a whole PDF file to the beginning of another PDF document. The other is to place a whole PDF document behind any specified page of another PDF document file, including the last page.
