Hi Adnan.

Here I have created a Bookmarks, Hyperlinks for which I have linked Named destinations.
I need to verify that those Bookmarks/Hyperlinks that I have created have Valid Named Destinations. If named destination exists, the page number the named destination is referring to exists in a pdf or no.

  • tenant_setup_tenant.pdf conatins valid bookmarks/links with valid named destinations
  • tenant_setup_tenant_invalid.pdf contains invalid bookmarks/links with invalid named destinations.

I have shared sample code with you. This will help you to identify named action exist or not in PDF.

string destinationName = "dest1";
Document doc = new Document("src.pdf");
if (doc.NamedDestinations[destinationName] !=null)
  Console.WriteLine("Destination exists");
  Console.WriteLine("Destination doe not exist");

Hi Adnan,
I have used the following code but I am getting this Exception

java.lang.NoClassDefFoundError: com/aspose/pdf/nameddestinations/NamedDestinationCollection

I am using 19.2 aspose.pdf version


Can you please try to use Aspose.PDF latest version 19.12 on your end and share feedback with us if there is still an issue.
