 Response.ContentType =   application / pdf; 
 Response.AddHeader（  content-disposition，  attachment; filename = TestPage.pdf）; 
 Response.Cache.SetCacheability（HttpCacheability.NoCache）; 
 StringWriter sw =  new  StringWriter（）; 
 HtmlTextWriter hw =  new  HtmlTextWriter（sw）; 
  this  .Page.RenderControl（hw）; 
 StringReader sr =  new  StringReader（sw.ToString（））; 
文件pdfDoc = 新文件（PageSize.A4,10f，10f，100f，0f）; 
 HTMLWorker htmlparser =  new  HTMLWorker（pdfDoc）; 
 PdfWriter.GetInstance（pdfDoc，Response.OutputStream）; 
 pdfDoc.Open（）; 
 htmlparser.Parse（sr）; 
 pdfDoc.Close（）; 
 Response.Write（pdfDoc）; 
 Response.End（）; 

请帮帮我。

代替htmlparser.Parse（sr）;

使用此



StringBuilder strB = new StringBuilder（ html）;

使用（TextReader sReader = new StringReader（strB.ToString（）））
 {
列出<   IElement  > 列表= HTMLWorker.ParseToList（sReader，new StyleSheet（））; 
 foreach（列表中的IElement elm）
 {
 Doc.Add（elm）; 
} 
} 

问候

In Place of "htmlparser.Parse(sr);"
Use this

StringBuilder strB = new StringBuilder(html);

using (TextReader sReader = new StringReader(strB.ToString()))
           {
               List<IElement> list = HTMLWorker.ParseToList(sReader, new StyleSheet());
               foreach (IElement elm in list)
               {
                   Doc.Add(elm);
               }
           }
