How to decide whether there really are bookmark involved?


Document pdfDocument = new Document(ABC.pdf);//ABC.pdf does not contain bookmarks .

if (pdfDocument.Outlines.Count>0 || pdfDocument.Outlines.First.Count > 0)//Outlines.Count | 1
{
try
{
Aspose.Pdf.Facades.PdfBookmarkEditor bookmarkEditor = new Aspose.Pdf.Facades.PdfBookmarkEditor();
bookmarkEditor.BindPdf(pdfDocument);
//Export bookmarks
bookmarkEditor.ExportBookmarksToXML(sOutpathFile);//The error occurred
}

catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
else
{
//
…
}

Hi Huang,


In order to get the Bookmark count, please try using following code snippet. In case I have not properly understood your requirement, please share some further details.

[C#]

//open document<o:p></o:p>

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document("c:/pdftest/ABC.pdf");

//loop through all the bookmarks

foreach (OutlineItemCollection outlineItem in pdfDocument.Outlines)

{

Console.WriteLine("Total Bookmark count " + outlineItem.Count);

}

Thank you!

I run your code!
outlineItem.Count | 0 // Why the Count is zero ?, The Attachment PDF file contains the bookmark.
outlineItem.Title | “A” //The bookmark name display correct.

Hi Huang,

Hi Huang,


Thanks for your patience In reference to above logged issue, we would like to update you that in loop outlineItem.Count returns count of subitems of current bookmark. In order to get bookmark count (more correct count of bookmarks of highest level), you may use:

Console.WriteLine(doc.Outlines.Count);


var doc = new Document(myDir

  • “bookmark.pdf”);<o:p></o:p>

//count of bookmarks at document level

Console.WriteLine(doc.Outlines.Count);

//loop through all the bookmarks

foreach (OutlineItemCollection outlineItem in doc.Outlines)

{

Console.WriteLine("Total child Bookmark count " + outlineItem.Count);

Console.WriteLine("Bookmark title " + outlineItem.Title);

}


Please feel free to contact us for any further assistance.


Best Regards,
