Thanks for contacting support.

Please check following code snippet to replace the URI of specific link annotation inside PDF document. For your reference, I have also attached an output, generated by below code snippet.

Document pdfDocument = new Document(dataDir + "testLink.pdf");
PageCollection pages = pdfDocument.Pages;

foreach (Page p in pages)
{
 foreach (Annotation anno in p.Annotations)
  {
    if (anno.AnnotationType == AnnotationType.Link)
     {
       LinkAnnotation linkAnno = (LinkAnnotation)anno;
        if (linkAnno.Action is GoToURIAction)
         {
           GoToURIAction goToAction = (GoToURIAction)linkAnno.Action;
           if (goToAction.URI == "http://www.google.com/")
              goToAction.URI = "http://www.aspose.com/";
         }
     }
  }
}
pdfDocument.Save(dataDir + "linktest_processed.pdf");
