在C＃中的iTextsharp中将html内容转换为pdf时，Bullet无效

Question

我在C＃中尝试过以下代码.Html内容有子弹，但事实并非如此     显示在创建的PDF文件中。在给定的例子中，我添加了两种类型的子弹，一种是unorderlist＆amp;另一个是订单。 你能帮我解决一下吗？

以下是代码：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DocToPdfConvertor;
using ClosedXML;
using ClosedXML.Excel;
using System.Configuration;
using iTextSharp.text.html.simpleparser;
using iTextSharp.text;
using iTextSharp.text.pdf;

namespace DocToPdfConvertor.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {

            // get the HTML code of this view
            string htmlToConvert = @"Types of fruits<div><ul><li>Apple</li><li>Mango</li><li>Banana</li></ul><div>Types of Vegetables</div></div><div><ol><li>Onion</li><li>Tomato</li><li>Potato</li></ol></div><div><br></div>";

            string filename = "PDFfile" + DateTime.Now.ToString("dd-MM-yyyy(hh-mm-sstt)") + ".pdf";           
            string filePath = ConfigurationManager.AppSettings["ProfileImages"];
            string fullpath = Path.Combine(filePath, filename);
            System.IO.File.WriteAllBytes(fullpath, GetPDF(htmlToConvert));         


            return View();
        }

        public byte[] GetPDF(string pHTML)
        {
            byte[] bPDF = null;

            MemoryStream ms = new MemoryStream();
            TextReader txtReader = new StringReader(pHTML);

            // 1: create object of a itextsharp document class
            Document doc = new Document(PageSize.A4,25, 25, 25, 25);

            FontFactory.RegisterDirectories();           

            // 2: we create a itextsharp pdfwriter that listens to the document and directs a XML-stream to a file
            PdfWriter oPdfWriter = PdfWriter.GetInstance(doc, ms);


            // 3: we create a worker parse the document
            HTMLWorker htmlWorker = new HTMLWorker(doc);


            // 4: we open document and start the worker on the document
            doc.Open();
            htmlWorker.StartDocument();

            // 5: parse the html into the document
            htmlWorker.Parse(txtReader);

            // 6: close the document and the worker
            htmlWorker.EndDocument();
            htmlWorker.Close();
            doc.Close();

            bPDF = ms.ToArray();

            return bPDF;
        }


    }
}
