无法使用C＃在asp.net中使用iTextSharp API将HTML标记导出为PDF？

我有一个HTML标记，其中包含HTML Table和Images 。 我正在使用iTextSharp API将HTML markup to PDF转换HTML markup to PDF 。 但是，遗憾的是iTextSharp无法将包含Images＆Table的HTML标记导出为PDF。

错误：找不到网络路径。

结果必须是：

码：

 using iTextSharp.text; using iTextSharp.text.pdf; using iTextSharp.text.html; using System.Data.SqlClient; using System.Text; using iTextSharp.text.html.simpleparser; public string strSelectUserListBuilder = @"

"; protected void HTMLToPDF() { String htmlText = strSelectUserListBuilder.ToString(); Document document = new Document(); PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "MySamplePDF.pdf", FileMode.Create)); document.Open(); iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document); hw.Parse(new StringReader(htmlText)); document.Close(); } protected void Page_Load(object sender, EventArgs e) { HTMLToPDF(); } 
  我知道这个错误是由于Image Path。  但是，无法解决。 
 任何方案？ 
 帮助感谢！

 看一下： 使用包含数据库中图像的itextsharp创建pdf 
 你需要在每个img元素的src属性中提供完整的物理路径（例如 ），或者有可能告诉iTextSharp物理所有图像的基本文件夹。

 我能够通过useiung特殊提供商正确呈现我的HTML 
 var baseUrl = string.Format("{0}://{1}", Request.Url.Scheme, Request.Url.Authority); var html = ...; Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); Response.ContentEncoding = Encoding.UTF8; Response.AddHeader("content-disposition", string.Format("attachment; filename={0}.pdf", fileName)); Response.ContentType = "application/pdf"; using (var ms = new MemoryStream()) { using (var doc = new Document()) { using (var writer = PdfWriter.GetInstance(doc, ms)) { doc.Open(); var rootProvider = new CustomRootProvider(baseUrl, Request.PhysicalApplicationPath); //Server.MapPath(Request.ApplicationPath) FontFactory.RegisterDirectories(); var htmlContext = new HtmlPipelineContext(null); htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory()); htmlContext.SetImageProvider(rootProvider); htmlContext.SetLinkProvider(rootProvider); htmlContext.CharSet(Encoding.UTF8); var cssResolver = XMLWorkerHelper.GetInstance().GetDefaultCssResolver(true); var pipeline = new CssResolverPipeline(cssResolver, new HtmlPipeline(htmlContext, new PdfWriterPipeline(doc, writer))); var worker = new XMLWorker(pipeline, true); var p = new XMLParser(worker); using(var htmlStream = new MemoryStream(Encoding.UTF8.GetBytes(html))) { p.Parse(htmlStream, Encoding.UTF8); } writer.CloseStream = false; } doc.Close(); } ms.Position = 0; Response.BinaryWrite(ms.ToArray()); } Response.Flush(); Response.End(); ... public class CustomRootProvider : AbstractImageProvider, ILinkProvider { private string _baseUrl; private string _basePath; public CustomRootProvider(string baseUrl, string basePath) { _baseUrl = baseUrl; } public override Image Retrieve(string src) { var siteUrl = string.IsNullOrEmpty(_baseUrl) ? HttpContext.Current.Request.Url.AbsoluteUri.Replace(HttpContext.Current.Request.Url.PathAndQuery, string.Empty) : _baseUrl; siteUrl = VirtualPathUtility.RemoveTrailingSlash(siteUrl); if (Uri.IsWellFormedUriString(src, UriKind.Relative)) { src = new Uri(new Uri(siteUrl), src).ToString(); } try { return Image.GetInstance(src); } catch (Exception) { return Image.GetInstance(new Uri(new Uri(siteUrl), "/Content/Images/noimage.png").ToString()); } } public override string GetImageRootPath() { return string.IsNullOrEmpty(_basePath) ? HttpContext.Current.Request.PhysicalApplicationPath : _basePath; //HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath); } public string GetLinkRoot() { return string.IsNullOrEmpty(_baseUrl) ? HttpContext.Current.Request.Url.AbsoluteUri.Replace(HttpContext.Current.Request.Url.PathAndQuery, string.Empty) : _baseUrl; } } 
 但是在某些主机上有html unicode符号的奇怪问题（在德国机器上确定但在俄语上呈现不正确）。 我试图用iTextSharp fontfactory注册不同的字体，以使用不同的标记（css规则，字体 – 面等）。 什么都没有帮助我。 最后使用wkhtmltopdf和包装器Pechkin （互联网上提供了不同的包装器）。  wkhtmltopdf开箱即用！： 
 var config = new GlobalConfig().SetMargins(0, 0, 0, 0).SetPaperSize(PaperKind.A4); var pdfWriter = new SynchronizedPechkin(config); var bytes = pdfWriter.Convert(new Uri(dataUrl)); Response.BinaryWrite(bytes); 
 极力推荐！
