In the following code , chinese font( contained html text) doesnot display in pdf generated.
I also try styles and font in this method. Please help to solve this problem.
Thanks in advance to all.

public static bool GeneratedPDF(string strHTMLText, string filename, string action, string rpttype)
    {
        bool blnReturn = false;

        string fontpath = HttpContext.Current.Server.MapPath("~/files/fonts/");
        string filepath = HttpContext.Current.Server.MapPath("~/files/pdf/");

        BaseFont customfont = BaseFont.CreateFont(fontpath + "simhei.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED); 

        Font font = new Font(customfont, 12);


        //List<iTextSharp.text.IElement> htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new System.IO.StringReader(strHTMLText), null);


        iTextSharp.text.Document document = new iTextSharp.text.Document();

        if (rpttype.Trim().ToUpper() == "REPORT")
            document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A2.Rotate());

        else if (rpttype.Trim().ToUpper() == "GRID")
            document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4.Rotate());

        else
            document = new iTextSharp.text.Document(iTextSharp.text.PageSize.LETTER);

        iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(document, new FileStream(filepath + "\\" + filename, FileMode.Create));
        document.Open();

        iTextSharp.text.html.simpleparser.StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();

        styles.LoadTagStyle("body", "font-family", "verdana");

        styles.LoadStyle("body", "font-size", "5px");


        List<iTextSharp.text.IElement> htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new System.IO.StringReader(strHTMLText), styles);
        for (int k = 0; k < htmlarraylist.Count; k++)
        {

            document.Add((IElement)htmlarraylist[k]);

        }

        iTextSharp.text.Paragraph p = new iTextSharp.text.Paragraph();

        p.InsertRange(0, htmlarraylist);

        p.Font = font; // font does not work 
        document.Add(p);

        document.Close();

        blnReturn = true;

        return blnReturn;
    }

    You set the StyleSheet wrong. It should be something like this:

    string html = @"
<html><body>    
<p>使用iText做PDF文件輸出</p>    
<p>使用iText做PDF文件輸出</p>    
<p>使用iText做PDF文件輸出</p>    
<p>使用iText做PDF文件輸出</p>    
<p>使用iText做PDF文件輸出</p> 
</body></html>   
";
FontFactory.Register("c:/windows/fonts/ARIALUNI.TTF"); 
StyleSheet style = new StyleSheet();
style.LoadTagStyle("body", "face", "Arial Unicode MS");
style.LoadTagStyle("body", "encoding", BaseFont.IDENTITY_H);
using (Document document = new Document()) {
  PdfWriter writer = PdfWriter.GetInstance(
    document, Response.OutputStream
  );
  document.Open();
  foreach(IElement element in HTMLWorker.ParseToList(
      new StringReader(html.ToString()), style))
  {
    document.Add(element);
  }
}

    You need to change the third parameter of LoadTagStyle() above to the correct name of the specific font you’re using. In other words, replace “Arial Unicode MS” above with the name/value for your font. Or you can use the font above too.
