使用iTextSharp将HTML转换为PDF时出现问题 [英] Problem with converting HTML to PDF with iTextSharp

问题描述

  protected   void  btnPdf_Click（对象发​​件人，EventArgs e）
 {
 字符串 attachment =    attachment; filename = +   D ：\ abc +  。pdf; 
 Response.ClearContent（）; 
 Response.AddHeader（  content-disposition，附件）; 
 Response.ContentType =   application / pdf; 
 StringWriter s_tw =  new  StringWriter（）; 
 HtmlTextWriter h_textw =  new  HtmlTextWriter（s_tw）; 
 h_textw.AddStyleAttribute（  font-size，  7pt）; 
 h_textw.AddStyleAttribute（  color，  黑色）; 
 Panel1.RenderControl（h_textw）;  //  面板名称 
文件doc =  new  Document（）; 
 doc =  new 文档（PageSize.A4， 5 ， 5 ， 15 ， 5 ）; 
 FontFactory.GetFont（  Verdana， 80 ，iTextSharp.text.Color.RED）; 
 PdfWriter.GetInstance（doc，Response.OutputStream）; 
 doc.Open（）; 
 StringReader s_tr =  new  StringReader（s_tw.ToString（））; 
 HTMLWorker html_worker =  new  HTMLWorker（doc）; 
 html_worker.Parse（s_tr）; 
 doc.Close（）; 
 Response.Write（doc）; 
} 

我使用了以下参考文献：

 使用 iTextSharp.text; 
 使用 iTextSharp.text.pdf; 
 使用 iTextSharp.text.html; 
 使用 iTextSharp.text.html.simpleparser; 
 使用 System.Drawing; 

在上面的编码中，要将网页（HTML输出）转换为PDF，我在html_worker.Parse（s_tr）;​​收到错误说找不到网络路径。

请帮助我

解决方案

Escape

  string  attachment =   attachment; filename = +   D：\abc +  。pdf; 

to

  string  attachment =   attachment; filename = +  @  D：\abc +  。 pdf; 

或

  string  attachment =    attachment; filename = +   D：\\abc +  。pdf; 

protected void btnPdf_Click(object sender, EventArgs e)
        {
            string attachment = "attachment; filename=" + "D:\abc" + ".pdf";
            Response.ClearContent();
            Response.AddHeader("content-disposition", attachment);
            Response.ContentType = "application/pdf";
            StringWriter s_tw = new StringWriter();
            HtmlTextWriter h_textw = new HtmlTextWriter(s_tw);
            h_textw.AddStyleAttribute("font-size", "7pt");
            h_textw.AddStyleAttribute("color", "Black");
            Panel1.RenderControl(h_textw);//Name of the Panel
            Document doc = new Document();
            doc = new Document(PageSize.A4, 5, 5, 15, 5);
            FontFactory.GetFont("Verdana", 80, iTextSharp.text.Color.RED);
            PdfWriter.GetInstance(doc, Response.OutputStream);
            doc.Open();
            StringReader s_tr = new StringReader(s_tw.ToString());
            HTMLWorker html_worker = new HTMLWorker(doc);
            html_worker.Parse(s_tr);
            doc.Close();
            Response.Write(doc);
}

I have used following References:

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html;
using iTextSharp.text.html.simpleparser;
using System.Drawing;

In the above coding, to convert a web page (HTML output) to PDF, I am getting an error at "html_worker.Parse(s_tr);" saying that "The network path was not found."
Kindly help me

解决方案

Escape

string attachment = "attachment; filename=" + "D:\abc" + ".pdf";

to

string attachment = "attachment; filename=" + @"D:\abc" + ".pdf";

or

string attachment = "attachment; filename=" + "D:\\abc" + ".pdf";
