我想以 pdf 格式导出我的 htmlcode

var document = new Document();
            string filePath = Server.MapPath("~/generatedBook");
            string exceptionPath = Server.MapPath("~/exceptions");
            PdfWriter pdfWriter = PdfWriter.GetInstance(document,
            new FileStream(filePath + "/Book"+_IdSes+".pdf", FileMode.Create));
            pdfWriter.SetFullCompression();
            pdfWriter.StrictImageSequence = true;
            pdfWriter.SetLinearPageMode();


            try
            {
                document.SetPageSize(PageSize.A4.Rotate());
                document.SetPageSize(new Rectangle(792f, 612f)); // 11" x 8.5"

//这里它给了我异常堆栈是空的

List<iTextSharp.text.IElement> htmlarraylist = 
 iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new 
                                         StringReader(htmlcode.ToString()), st);

//htmlcode 是 StringBuilder 类型

foreach (IElement t in htmlarraylist)
                {
                    document.Add((IElement)t);
                }


                document.Close();

完全例外 

System.InvalidOperationException: Stack empty.
   at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
   at System.Collections.Generic.Stack`1.Pop()
   at iTextSharp.text.html.simpleparser.HTMLWorker.EndElement(String tag)
   at iTextSharp.text.xml.simpleparser.SimpleXMLParser.ProcessTag(Boolean start)
   at iTextSharp.text.xml.simpleparser.SimpleXMLParser.Go(TextReader reader)
   at iTextSharp.text.xml.simpleparser.SimpleXMLParser.Parse(ISimpleXMLDocHandler doc,          
   ISimpleXMLDocHandlerComment comment, TextReader r, Boolean html)
   at iTextSharp.text.html.simpleparser.HTMLWorker.Parse(TextReader reader)

任何的想法？提前致谢

HTMLWorker 已被弃用，不会被维护。它已被 xml-worker 取代。
