Question

我正在使用Itextsharp将html转换为pdf。我的html使用的是框架和CSS。主页面是ConvertHTMLToPDF.htm，它使用的是frame1.htm，frame2.htm和一个文件style.css。我正在使用Itextsharp将此html页面转换为pdf。虽然我能够将html转换为pdf，但它只将我的ConvertHTMLToPDF.htm转换为pdf。相关的frame1.htm，frame2.htm和style.css未嵌入pdf文件中。

///这是我将html转换为pdf的代码，其中ltrlReeport是包含html的文字。

 public void CreatePDFFromHTMLFile()
        {
            try
            {

                string a = WebUtility.HtmlEncode(ltrlReeport.Text);
                a = a.Replace("\r\n", "");
                a = a.Replace("\0", "");
                StreamReader strmRdr = new StreamReader(a);

                Document doc = new Document(iTextSharp.text.PageSize.A4);   

                PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream("F:\\aTestFile.pdf", FileMode.Create));

                doc.Open();

                HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
                htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());

                ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(true);

                IPipeline pipeline = new CssResolverPipeline(cssResolver, new  HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, wri)));

                XMLWorker worker = new XMLWorker(pipeline, true);
                XMLParser p = new XMLParser(worker);

                TextReader tr = new StringReader(ltrlReeport.Text);
                p.Parse(tr);
                doc.Add(new Paragraph("hello"));
                doc.Close();
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

无法将ConvertHTMLToPDF.htm转换为PDF;在asp / c中使用itextsharp＃
