Reg：输入字符串的格式正确 [英] Reg: Input string was in correct format

问题描述

Hai我在这里将div转换成pdf格式。\



这是我的代码

 Response.ContentType =application / pdf; 
 Response.AddHeader（content-disposition，attachment; filename = UserDetails.pdf）; 
 Response.Cache.SetCacheability（HttpCacheability.NoCache）; 
 StringWriter sw = new StringWriter（）; 
 HtmlTextWriter hw = new HtmlTextWriter（sw）; 
 this.InvoiceBody.RenderControl（hw）; 
 StringReader sr = new StringReader（sw.ToString（））; 
文件pdfDoc =新文件（PageSize.A4,10f，10f，100f，0.0f）; 
 HTMLWorker htmlparser = new HTMLWorker（pdfDoc）; 
 PdfWriter.GetInstance（pdfDoc，Response.OutputStream）; 
 pdfDoc.Open（）; 
 htmlparser.Parse（sr）; 
 pdfDoc.Close（）; 
 Response.Write（pdfDoc）; 
 Response.End（）; 
 

这里我收到错误输入字符串格式不正确。



请帮帮我

解决方案

 htmlparser.Parse（sr）; 

它写的是StringReader Class而不是html字符串，

u甚至可以直接绑定sw.toString（）或者使用sr.toString（）

Hai here i am converting a total div to pdf format.\

This is my code

Response.ContentType = "application/pdf";
       Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
       Response.Cache.SetCacheability(HttpCacheability.NoCache);
       StringWriter sw = new StringWriter();
       HtmlTextWriter hw = new HtmlTextWriter(sw);
       this.InvoiceBody.RenderControl(hw);
       StringReader sr = new StringReader(sw.ToString());
       Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0.0f);
       HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
       PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
       pdfDoc.Open();
       htmlparser.Parse(sr);
       pdfDoc.Close();
       Response.Write(pdfDoc);
       Response.End();

Here i am getting the error Input string was incorrect format.

Please help me

解决方案

htmlparser.Parse(sr);

it is writing StringReader Class not html string,
u can even directly bind sw.toString() or make that sr.toString()
