iTextSharp v5 GetTextFromPage（）抛出IndexOutOfRangeException

Question

Trying to extract the textual content of a pdf with the following code:

PdfReader reader = new PdfReader(path);
string strText = string.Empty;

for (int page = 1; page <= reader.NumberOfPages; page++)
{
    string s = PdfTextExtractor.GetTextFromPage(reader, page);
    strText += " " + s;                
}
reader.Close();

NumberOfPages returns 257, but at page 227, GetTextFromPage() throws a IndexOutOfRangeException.

Any help is appreciated.
