Hi Marcus,


Greetings from Syncfusion.


Please find the code snippet for swapping the bookmark name in the PdfLoadedDocument:


//Loads the PDF document.

PdfLoadedDocument document = new PdfLoadedDocument(DataPathOutput + "Output.pdf");


//Gets all the bookmarks.

PdfBookmarkBase bookmarks = document.Bookmarks;


//Gets the first two bookmark and its Title.

PdfLoadedBookmark bookmark1 = bookmarks[0] as PdfLoadedBookmark;

string title1 = bookmark1.Title;


PdfLoadedBookmark bookmark2 = bookmarks[1] as PdfLoadedBookmark;

string title2 = bookmark2.Title;


//Swapping the title name of the first two bookmarks

bookmark1.Title = title2;

bookmark2.Title = title1;


//Saves the document




Sample for the same can be downloaded from below link:
