I have used the following codes, but it does work:

string filename = "Bookmarks.pdf";
PdfDocument document = PdfReader.Open(filename, PdfDocumentOpenMode.Modify);

PdfOutline.PdfOutlineCollection outlines = document.Outlines;

Console.Writeline(outlines.Count);

The outlines.Count always return 0.

I did pretty much the same thing. Ran the Bookmarks example and then used the output file to try to read in the outlines in order to split the file. But I'm getting a count of 0 (zero) as well.

I got the same kind of error.
Open an existing PDF that has outlines and the PdfDocument.Outlines.Count is zero.
My guess is the PdfDocument.Outlines only knows the outlines during the PDF creation. During the PDF import the Outlines property do not get populated. If this is true then PdfSharp documentation is very very poor.
To access the Outlines of the PdfDocument, use the following:
PdfDocument.Internals.Catalog.Elements.GetObject("/Outlines") and cast the output object to PdfOutline.
To access the title of the outline use PdfOutline.Elements.GetString("/Title")

(PS: these can be found in the source code of the project PdfMerge).

Yes.

The PdfOutline object contains Outlines. This allows to create a tree of Outlines.

Not my area of expertise, but I guess bun_zee's post shows how to do that.
