Getting annotations out of an existing PDF

[rdenne]

I was trying to use PdfSharp to retrieve comments from a PDF and save as XML.  But I find that I get exceptions thrown if I try this code:

PdfDocument doc = PdfReader.Open(filename,
  PdfDocumentOpenMode.ReadOnly);
for (int pgCt = 0; pgCt < doc.PageCount; pgCt++)
{
  PdfPage pg = doc.Pages[pgCt];
 
  for (int annCt = 0; annCt < pg.Annotations.Count;
    annCt++)
  {
    PdfAnnotation ann = pg.Annotations[annCt];
    SWF.MessageBox.Show(ann.Contents);
  }
}

I get a System.InvalidCastException thrown in PdfDictionary at line 654.  The problem is that the value is a PdfArray and cannot be casted to a PdfDictionary ref.

I have looked at the sample Annotations class, but that works fine since it just adds a new PdfPage and then adds annotations to that new page.

Any help?

Thanks

Should work with beta 3. If not, send us the PDF file.
