[英]aspx to pdf using itextSharp 5.3.0
我正在使用此dll iTextSharp 5.3.0制作pdf文件。 有沒有辦法在pdf中轉換完整的.aspx頁? 我的頁面有網格和服務器端代碼。
這是我的代碼:
受保護的無效Button1_Click(對象發送者,EventArgs e){
createPDF(Server.MapPath("Default.aspx"));
}
private void createPDF(string html)
{
TextReader reader = new StringReader(html);
// step 1: creation of a document-object
Document document = new Document(PageSize.A4, 30, 30, 30, 30);
// step 2:
// we create a writer that listens to the document
// and directs a XML-stream to a file
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("c://test.pdf", FileMode.Create));
HTMLWorker worker = new HTMLWorker(document);
document.Open();
worker.StartDocument();
List<IElement> p = HTMLWorker.ParseToList(new StreamReader(html), new StyleSheet());
for (int k = 0; k < p.Count; k++)
{
document.Add((IElement)p[k]);
}
worker.EndDocument();
worker.Close();
document.Close();
}
它正在工作,但是文件test.pdf只是純文本。 html解釋不正確,我的網格丟失了,服務器端值(來自網格的值)也丟失了。 我還嘗試了以下代碼: http : //forums.asp.net/t/1199774.aspx以及此處: Itextsharp中的HTMLParser問題
提前致謝!
這是我的誠實建議! 不要在HTMLWorker.ParseToList上浪費時間。 它具有非常基本的HTML解析器。 試試這個包,您將永遠不會回頭! https://github.com/pruiz/WkHtmlToXSharp
ITextSharp僅渲染內聯CSS,添加CSS文件時出現問題。
System.Web.HttpContext.Current.Response.ContentType = "application/pdf";
System.Web.HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=BookingDetails.pdf");
System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
this.CreateBookingMainDiv.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(new Rectangle(922,1296),7f,7f,7f,0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, System.Web.HttpContext.Current.Response.OutputStream);
pdfDoc.Open();
//HtmlPipeline
CssAppliers ca = new CssAppliersImpl();
//ICssFile cfile = new CssFileProcessor();
HtmlPipelineContext htmlContext = new HtmlPipelineContext(ca);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
//CSS stuff
//var cssResolver = new StyleAttrCSSResolver();
//var DamcoCss = XMLWorkerHelper.GetCSS(new FileStream(HttpContext.Current.Server.MapPath("~/css/damco.css"), FileMode.Open));
ICssFile cfile = new CssFileImpl();
ICSSResolver cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(true);
//String DamcoCss = HttpContext.Current.Server.MapPath("~/css/damco.css");
//String BootStrapCss = HttpContext.Current.Server.MapPath("~/css/bootstrap.css");
//String BootStrapCssTheme = HttpContext.Current.Server.MapPath("~/css/bootstrap-theme.css");
//Add the external CSS file
//cssResolver.AddCssFile(DamcoCss, true);
//cssResolver.AddCssFile(BootStrapCss, true);
//cssResolver.AddCssFile(BootStrapCssTheme, true);
//Pipeline
IPipeline pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(pdfDoc, writer)));
//XMLWorker
XMLWorker worker = new XMLWorker(pipeline, true);
//and...we parse
XMLParser parser = new XMLParser(true, worker);
//parser.AddListener(worker);
parser.Parse(sr);
parser.Flush();
pdfDoc.Close();
System.Web.HttpContext.Current.Response.Write(pdfDoc);
System.Web.HttpContext.Current.ApplicationInstance.CompleteRequest();
//System.Web.HttpContext.Current.Response.End();
使用XMLWorker而不是HTMLWorker。 就像魅力。
