将Asp.Panel导出为PDF？

我想将带有CSS的Asp.Panel content(text, GridViews)从C＃.NET导出为PDF。 我正在使用带有Asp.Panel的iTextSharp和RenderControl，但CSS不是以PDF格式呈现的。

如何解决此问题（使用iTextSharp（如果可能）或以其他方式）？

此代码生成PDF文件：

  StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); StringReader sr; string fileName = "C://pdf/GridView.pdf"; var doc = new Document(PageSize.A3, 45, 5, 5, 5); var pdf = fileName; PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(pdf, FileMode.Create)); doc.Open(); HtmlPipelineContext htmlContext = new HtmlPipelineContext(null); htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory()); ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false); cssResolver.AddCssFile(Server.MapPath("Content/PDFs.css"), true); IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, writer))); XMLWorker worker = new XMLWorker(pipeline, true); XMLParser xmlParse = new XMLParser(true, worker); this.pnlTabs.RenderControl(htw); sr = new StringReader(sw.ToString()); xmlParse.Parse(sr); xmlParse.Flush(); doc.Close(); 

这是我要发送给PDF的ASP面板：

如果要使用带有css的ITextSharp导出为pdf，还有一个额外的下载（XMLWorker）。 您可以从此处获取XMLWorker

要将其设置为应用您的CSS，您需要执行以下操作

  StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); StringReader sr; string fileName = Server.MapPath("PATH TO PDF"); var doc = new Document(PageSize.A3, 45, 5, 5, 5); var pdf = fileName; PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(pdf, FileMode.Create)); doc.Open(); HtmlPipelineContext htmlContext = new HtmlPipelineContext(null); htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory()); ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(false); cssResolver.AddCssFile(Server.MapPath("PATH TO CSS"), true); IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, writer))); XMLWorker worker = new XMLWorker(pipeline, true); XMLParser xmlParse = new XMLParser(true, worker); control.RenderControl(htw); sr = new StringReader(sw.ToString()); xmlParse.Parse(sr); xmlParse.Flush(); 

使用相关文件路径替换PATH TO PDF （保存文件的loacation）和PATH TO CSS （位置是您的css文件）。 当我不得不这样做时，css文件必须是一个外部文件（.css）。
