Dear GHWels,

Thanks for your inquiry.
Here is sample code for your reference:

Code: Select all

            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(FilePath + "sample1.pdf");           
            PdfDocument newPdf = new PdfDocument();           
            foreach (PdfPageBase page in doc.Pages)
            {
                //Create a new PDF page with Page size =A4 and PDFMargins at 0.
                PdfPageBase newPage = newPdf.Pages.Add(PdfPageSize.A4, new PdfMargins(0));
                PdfTextLayout loLayout = new PdfTextLayout();
                loLayout.Layout = PdfLayoutType.OnePage;

                //Copy the contents of page into the new PDF page at the PointF(0,0)
                page.CreateTemplate().Draw(newPage, new PointF(0, 0), loLayout);
            }
            //save the resized PDF to stream
            MemoryStream s = new MemoryStream();
            newPdf.SaveToStream(s);
           
            //open another PDF
            FileStream s1 = File.OpenRead(FilePath + "sample2.pdf");
            Stream[] streams = { s1, s };
            //merge documents by stream
            PdfDocumentBase resultPdf = PdfDocument.MergeFiles(streams);
            resultPdf.Save("8145.pdf", FileFormat.PDF);
