Assuming you are talking about comments. Try the following:

for (int i = pageFrom; i <= pageTo; i++) {
    PdfDictionary page = reader.GetPageN(i);
    PdfArray annots = page.GetAsArray(iTextSharp.text.pdf.PdfName.ANNOTS);
    if (annots!=null)
        foreach (PdfObject annot in annots.ArrayList) {
            PdfDictionary annotation = (PdfDictionary)PdfReader.GetPdfObject(annot);
            PdfString contents = annotation.GetAsString(PdfName.CONTENTS);
            // now use the String value of contents
        }
    }
}


This is written from memory (I'm a Java developer, not a C # developer).
