如何使用iTextSharp的html页面转换成用CSS PDF？

问题描述：

这是我的code：

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());

Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);

HTMLWorker htmlparser = new HTMLWorker(pdfDoc);

PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

pdfDoc.Open();

**htmlparser.Parse(sr);** //the exception here

pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();

该错误是：

无法投类型的对象iTextSharp.text.html.simpleparser.CellWrapper到类型
iTextSharp.text.Paragraph。

Unable to cast object of type 'iTextSharp.text.html.simpleparser.CellWrapper' to type 'iTextSharp.text.Paragraph'.

这是什么例外？

答

我不知道这是不是答案，但我发现，iTextSharp的是挑剔有有效的HTML。我的测试已经被打开两次，从不关闭，并且花了大约一个小时，我注意到一个表。唯一的例外是非常相似，你必须有一个。

I don't know if this is the answer, but I found that iTextSharp is picky about having valid html. My tests had a table that was opened twice and never closed and that took about an hour for me to notice. The exception was very similar to the one you have there.
