Can't extract highlighted text

Hello sir

I’m trying to extract highlighted text.
You can see Yellow highlighted text in my pdf.


I want to get text “TEST1” and “TEST2” but
getMaredText and GetMarkedTextFragments doesn’t work.
Let me know how to solve this problem and have a nice day~

  • here is my code
    foreach (var p in pages)
    foreach (Annotation ann in p.Annotations)
    if(ann.AnnotationType == AnnotationType.Highlight)
    HighlightAnnotation highlightAnnotation = ann as HighlightAnnotation;

                      string b = highlightAnnotation.GetMarkedText();
                      TextFragmentCollection collection =  highlightAnnotation.GetMarkedTextFragments();
                      string text = string.Empty;
                      foreach(TextFragment tf in collection)
                          text += tf.Text;
                      string a = "a";
