Hi all,

        {
            PdfReader rd = new PdfReader(_filePath);
            int pageNumber = 1;

            string oContent = "";
            while (pageNumber <= rd.NumberOfPages)
            {
                oContent += PdfString.STREAM.ToString();

答

PdfReader reader = new PdfReader(path);
 StringWriter output = new StringWriter();
 for (int i = 1; i <= reader.NumberOfPages; i++)
 {
     Paragraph o = CreateSimpleHtmlParagraph(output.ToString());
     output.WriteLine(PdfTextExtractor.GetTextFromPage(reader, i, new SimpleTextExtractionStrategy()));
 }
