现在当我尝试使用以下代码打印itex-sharp pdf时：

and now when I trying to print in itex-sharp pdf using below code :

 var doc = new iTextSharp.text.Document();
            doc.Open();

            iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
            ST.LoadTagStyle(HtmlTags.BODY, HtmlTags.ENCODING, BaseFont.IDENTITY_H);

            var tmpCellNote = new PdfPCell(new Phrase("Subcontractor Notes: ", noteFont)) { Border = 0, HorizontalAlignment = Element.ALIGN_LEFT, Colspan = 5 };
            tmpCellNote.PaddingLeft = (10 * schedule.Level);
            var objects = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(Convert.ToString(schedule.Notes)), ST);
            for (int k = 0; k < objects.Count; ++k)
            {
                tmpCellNote.AddElement((IElement)objects[k]);
            }
            table.AddCell(tmpCellNote);

            doc.Add(table);

使用上面的代码，它将打印如下：

using above code, it will printing like this:

• sf f


• sd gmdslkg 


• dsg 


• ffg 


• dfg g fdghdf
  
• dsg  g


• fdgh d


• ghdf rfh 
  
• hdf


• fdg dfghh


• bh dfh


• dfgh dfh 


• dfg 


• dfg dfghd r re 5ygtr  ger


• gds mgds


• dsfg sdg

• sf f
• sd gmdslkg  
• dsg 
• ffg 
• dfg g fdghdf
• dsg  g
• fdgh d
• ghdf rfh 
• hdf
• fdg dfghh
• bh dfh
• dfgh dfh 
• dfg 
• dfg dfghd r re 5ygtr  ger
• gds mgds
• dsfg sdg

1. dslmg lmdsg


2. dsg 


3.   grews


4. dgds g 


5. gsrd h


6.  例如dsg w r4ewty 43 dfgbreg


7.   t43 t43tgfdfsgre

1. dslmg lmdsg
2. dsg 
3.  grews
4. dgds g 
5. gsrd h
6.  eg dsg w r4ewty 43 dfgbreg
7.  t43 t43tgfdfsgre

那么，如何使用c＃和itextsharp PdfPTable和PdfPCell实现嵌套< ul> 和< li> 标签？

So,how can I achieve this using c# and itextsharp PdfPTable and PdfPCell for nested <ul> and <li> tags ?

请帮帮我。

谢谢。

推荐答案

ITextSharp库不支持。

It is not supported in ITextSharp library.

说实话，我不喜欢ITextSharp。从HTML中保存PDF需要做很多工作。我一直在使用的是Nreco.PdfGenerator，在这里找到：

To be honest, I don't like ITextSharp. Takes so much work to save PDF from HTML. What I'm always using is Nreco.PdfGenerator, found here:

PDF GENERATOR

现在，它支持嵌入式CSS，内联CSS，CSS分页，CSS表格行为设置，以及所有内容。您可以免费获得的最佳工具 - > PDF转换。

Now, it supports embedded CSS,inline CSS, page breaking by CSS, table behaviour setting by CSS, well, everything. Best tool you could ever find for free to get HTML -> PDF conversion.

从HTML生成pdf的示例代码：

Example code for generating pdf from HTML:

var generator = new NReco.PdfGenerator.HtmlToPdfConverter();
var fileLines = System.IO.File.ReadAllText(@"C:\TEMP\test.html"); //you can always use ANY html string, not exactly file
var pdfBytes = generator.GeneratePdf(fileLines); //returns PDF byte[]
System.IO.File.WriteAllBytes(@"C:\TEMP\test.pdf", pdfBytes); //save to PDF

使用您的示例我得到与HTML结果相同的PDF结果。

Using your example I got same PDF result as HTML result.
