Hi

while trying to update links on pdf (LinkAnnotation) , sometimes the action is null

and then trying to use the destination value instead (NamedDestination) I get the value of something like : {d0e74} which I dont know what it means

can anybody help me with this?

appreciate your help

LinkAnnotation linkAnno = (LinkAnnotation)i;

if (linkAnno.Action != null)

{

if (linkAnno.Action.GetType().Name == “GoToRemoteAction”)

{

}

else if (linkAnno.Action.GetType().Name == “GoToURIAction”)

{

uriAction = ((GoToURIAction)linkAnno.Action);

string n = uriAction.URI;

Console.WriteLine(">>>>" + n);

Logger.LogMessage(">>>>" + n);

Console.WriteLine(" ------- " + docName);

Logger.LogMessage(" ------- " + docName);

}

}

else if (linkAnno.Destination is ExplicitDestination)

{

ExplicitDestination explicitDest = (ExplicitDestination)linkAnno.Destination;

System.Console.WriteLine("{0}[{1}]", i, explicitDest.PageNumber);

}

else if (linkAnno.Destination is NamedDestination)

{

NamedDestination namedDest = (NamedDestination)linkAnno.Destination;

System.Console.WriteLine("{0}[{1}]", i, doc.Destinations.GetPageNumber(namedDest.Name, false));

}

Hi Iris,

Thanks for sharing the resource file.

I have tried accessing the hyperlink inside PDF file on page 30 and I am getting IndexOutOfRangeException. Can you please share some sample project, so that we can test the scenario in our environment. We are sorry for this inconvenience.

[C#]

using (Document pdfDocument = new Document("c:/pdftest/CA494-18500±+In-Mold+Labeling+(IML)+for+HP+Indigo+L%26P+How+to+Guide.pdf"))
{
    Console.WriteLine(pdfDocument.Pages[30].Annotations[1]);

    LinkAnnotation linkAnno = (LinkAnnotation)pdfDocument.Pages[30].Annotations[5];

    if (linkAnno.Action != null)
    {
        if (linkAnno.Action.GetType().Name == "GoToRemoteAction")
        {
            // Console.WriteLine("LinkAnnotation >>>> GoToRemoteAction");
        }
        else if (linkAnno.Action.GetType().Name == "GoToURIAction")
        {
            GoToURIAction uriAction = (GoToURIAction)linkAnno.Action;
            string uri = uriAction.URI;

            Console.WriteLine(">>>> " + uri);
            // Logger.LogMessage(">>>> " + uri);

            Console.WriteLine(" ------- " + pdfDocument.FileName);
            // Logger.LogMessage(" ------- " + docName);
        }
    }
    else if (linkAnno.Destination is ExplicitDestination explicitDest)
    {
        Console.WriteLine("{0}[{1}]", pdfDocument.Pages[30].Annotations[5], explicitDest.PageNumber);
    }
    else if (linkAnno.Destination is NamedDestination namedDest)
    {
        Console.WriteLine("{0}[{1}]", pdfDocument.Pages[30].Annotations[5],
            pdfDocument.Destinations.GetPageNumber(namedDest.Name, false));
    }

    pdfDocument.Save("c:/pdftest/LinkUpdated.pdf");
}

attach a simple console application project with main and only file
