    /// document as an attachment to the browser
    /// </summary>
    private void ConvertURLToPDF()
    {

        // Create the PDF converter. Optionally you can specify the virtual browser
        // width as parameter. 1024 pixels is default, 0 means autodetect
        PdfConverter pdfConverter = new PdfConverter();

        // set the license key - required
        pdfConverter.LicenseKey = "you license here";

        // set if header and footer are shown in the PDF - optional - default is false
        pdfConverter.PdfDocumentOptions.ShowHeader = false;
        pdfConverter.PdfDocumentOptions.ShowFooter = false;

            pdfConverter.ActiveXEnabled = false;
        }
        else

        }

        // set if the images in PDF are compressed with JPEG to reduce the PDF document size - optional - default is true
        pdfConverter.PdfDocumentOptions.JpegCompressionEnabled = true;

        // enable auto-generated bookmarks for a specified list of tags (e.g. H1 and H2)
        if (false)
        {
            pdfConverter.PdfBookmarkOptions.TagNames = new string[] { "H1", "H2" };
        }

        // set PDF security options - optional
        //pdfConverter.PdfSecurityOptions.CanPrint = true;

        //set PDF document description - optional
        //pdfConverter.PdfDocumentInfo.AuthorName = "Winnovative HTML to PDF Converter";

        //// add HTML header
        //if (cbAddHeader.Checked)
        //    AddHeader(pdfConverter);
        //// add HTML footer
        //if (cbAddFooter.Checked)
        //    AddFooter(pdfConverter);

        // Performs the conversion and get the pdf document bytes that you can further
        // save to a file or send as a browser response
        byte[] pdfBytes = pdfConverter.GetPdfBytesFromUrl(urlToConvert);

        // send the PDF document as a response to the browser for download
        System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
        response.Clear();
        response.AddHeader("Content-Type", "binary/octet-stream");
        response.AddHeader("Content-Disposition",
            "attachment; filename=ConversionResult.pdf; size=" + pdfBytes.Length.ToString());
        response.Flush();
        response.BinaryWrite(pdfBytes);
        response.Flush();
        response.End();
    }

祝你好运.
