Answer 1

Make sure you're running an iTextSharp version greater than 5.1, which had a bug that exactly matches your problem:

• iTextSharp v5 GetTextFromPage() throws IndexOutOfRangeException
• Index was outside the bounds of the array while reading a .Pdf using iTextSharp

Just tested with 5.5.4.0 (latest version), using this code, which works:

    StringBuilder sb = new StringBuilder();
// substitute 'pdfPath' with path to YOUR PDF
    PdfReader reader = new PdfReader(pdfPath);
    int pageNumber = 1;
    while (pageNumber <= reader.NumberOfPages) {
      sb.Append(PdfTextExtractor.GetTextFromPage(reader, pageNumber));
      ++pageNumber;
    }
