打开PDF的浏览器，而不是下载它的 [英] Opening a PDF in browser instead of downloading it

问题描述

我使用iTextSharp的打印面板插入按钮点击PDF。点击按钮之后，将PDF被下载到客户端的计算机。取而代之的是我需要的PDF在浏览器中，而不是下载打开。来自浏览器的用户将能够在PDF下载到他的计算机。

我用下面的code：

  Response.ContentType =应用程序/ PDF
Response.AddHeader（内容处置，附件;文件名=+文件名+.PDF）;
Response.Cache.SetCacheability（HttpCacheability.NoCache）;
StringWriter的SW =新的StringWriter（）;
HtmlTextWriter的HW =新的HtmlTextWriter（SW）;
pnl_print.RenderControl（HW）;StringReader SR =新StringReader（sw.ToString（））;
文档pdfDoc =新的文档（PageSize.A4，10F，10F，100F，0F）;
HTMLWorker的HTMLParser =新HTMLWorker（pdfDoc）;
PdfWriter.GetInstance（pdfDoc，Response.OutputStream）;
pdfDoc.Open（）;
htmlparser.Parse（SR）;
pdfDoc.Close（）;
的Response.Write（pdfDoc）;
到Response.End（）;sr.Close（）;
hw.Close（）;
sw.Close（）;
 

解决方案

的内容处置更改为在线而不是附件。

那么你的代码片段的第二行是

  Response.AddHeader（内容处置，内联;文件名=+文件名+.PDF）;
 

请参阅Content-Disposition:What是的＆QUOT的差异;内联＆QUOT;和＆QUOT;附件＆QUOT;？进一步的细节。

I'm using iTextSharp to print a panel into PDF on button click. After clicking on the button, the PDF is downloading to the client's computer. Instead of this I need the PDF to be opened in a browser instead of downloading. From the browser the user will be able to download the PDF to his PC.

I'm using the following code:

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=" + filename + ".pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
pnl_print.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();

sr.Close();
hw.Close();
sw.Close();

解决方案

Change the content-disposition to inline instead of attachment.

The second line of your snippet would then be

Response.AddHeader("content-disposition", "inline;filename=" + filename + ".pdf");

See Content-Disposition:What are the differences between "inline" and "attachment"? for further details.
