使用C＃ - 尝试将网页导出为pdf [英] Using C# - trying to export a webpage to pdf

问题描述

我正在使用Itextsharp

这是我在按钮点击时使用的代码：

 Response.ContentType =   application / pdf; 
 Response.Clear（）; 
 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（）; 
 

当我运行它时，我收到一个错误：路径中的非法字符

解决方案

I am using Itextsharp
Here is the code I am using at the button click:

Response.ContentType = "application/pdf";
Response.Clear();
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);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();

When I run it I get an error: "Illegal characters in path"
