PDFsharp & MigraDoc Foundation

I have a collection of PDF Files. Each PDF File has different number of multiple pages. I add bookmark to all PDF Files. After that i have to merge them in a single file but after doing so all the bookmarks gets removed. Please help me where im doing wrong. Im a newbie in development and found PDFSharp very easy to use My code is written below:


//Adding bookmarks to all the documents
foreach (string pdfFile in pdfFiles)
{
PdfDocument inputPDFDocument = PdfReader.Open(pdfFile, PdfDocumentOpenMode.Modify);
XFont font = new XFont("Verdana", 12);

PdfPage page = inputPDFDocument.Pages[0];
XGraphics gfx = XGraphics.FromPdfPage(page);
gfx.DrawString(PageName, font, XBrushes.Black, 40, 30, XStringFormats.Default);
// Create the root bookmark. You can set the style and the color.
PdfOutline outline = inputPDFDocument.Outlines.Add(PageName, page, true, PdfOutlineStyle.Bold, XColors.Red);
inputPDFDocument.Save(pdfFile);
}


//Merge all the docs into one doc
PdfDocument outputPDFDocument = new PdfDocument();

foreach (string pdfFile in pdfFiles)
{
PdfDocument inputPDFDocument = PdfReader.Open(pdfFile, PdfDocumentOpenMode.Import);

outputPDFDocument.Version = inputPDFDocument.Version;
foreach (PdfPage page in inputPDFDocument.Pages)
{
outputPDFDocument.AddPage(page);
}
}

Hi!
I don't know.
But it would be more efficient to merge the documents first and then add the bookmarks in a single program. This would also avoid the problem you have now.

I'm not sure whether this can be done with the Import option. It may require two steps (import all pages and save the file; open file, add labels and bookmarks, and save the file again (remember filenames and page counts during first step)).
It'll work using the technique shown in the Two Pages on One sample.

Thanks Thomas. I have already done it in the same way. Can we add bookmarks to nested n level. I mean child bookmarks to some level like minimum 3 or 4. As i have not found any help regarding this on PDFSharp. One can only add title bookmark and Children upto 1 level. i want to go for 3 or 4 levels. Is it possible?

You can create as many levels as you need.

Here's a code snippet from MigraDoc:
