并非所有HTML页面都无法通过SelectPdf转换为PDF

Question

I am using the following code to convert large HTML content to PDF using iTextSharp SelectPDF. None of the HTML pages are correctly converted. The data vanishes after 6 pages into the PDF.

public static void CreatePDFFromHTMLFile(string HtmlStream, string FileName)
    {
        try
        {
            // read parameters from the webpage
            string htmlString = HtmlStream;
            string baseUrl = "";
            string pdf_page_size = "A4";
            PdfPageSize pageSize = (PdfPageSize)Enum.Parse(typeof(PdfPageSize),
                pdf_page_size, true);
            string pdf_orientation = "Portrait";
            PdfPageOrientation pdfOrientation =
                (PdfPageOrientation)Enum.Parse(typeof(PdfPageOrientation),
                pdf_orientation, true);
            int webPageWidth = 1024;
            int webPageHeight = 0;
            HtmlToPdf converter = new HtmlToPdf();
            // set converter options
            converter.Options.PdfPageSize = pageSize;
            converter.Options.PdfPageOrientation = pdfOrientation;
            converter.Options.WebPageWidth = webPageWidth; 
            converter.Options.WebPageHeight = webPageHeight;
            // create a new pdf document converting an url
            PdfDocument doc = converter.ConvertHtmlString(htmlString, baseUrl);
            doc.Save(FileName);
            doc.Close();
        }
        catch (Exception ex)
        {
            Tracing.HandleException(ex);
        }
    }

Answer 1

之所以发生这种情况，是因为您使用的是SelectPdf社区版本，该版本是免费的，其局限性是您最多只能转换为5-6页的pdf，如果您需要的更多，则需要使用非免费版本。从这里https://selectpdf.com/downloads/

Answer 2

The problem is that you are using SelectPdf community edition. According to SelectPdf ( http://selectpdf.com/community-edition/ ), the free version is limited to 5 pages.

If you want to convert longer pages, you need to use the commercial edition, but that is not free.
