如何在新标签或窗口中打开PDF文件，而不是（使用asp.net）下载呢？ [英] How to open PDF file in a new tab or window instead of downloading it (using asp.net)?

问题描述

这是code下载该文件。

This is the code for downloading the file.

System.IO.FileStream fs = new System.IO.FileStream(Path+"\\"+fileName, System.IO.FileMode.Open, System.IO.FileAccess.Read);
byte[] ar = new byte[(int)fs.Length];
fs.Read(ar, 0, (int)fs.Length);
fs.Close();

Response.AddHeader("content-disposition", "attachment;filename=" + AccNo+".pdf");
Response.ContentType = "application/octectstream";
Response.BinaryWrite(ar);
Response.End();

在执行此code，它会要求用户打开或保存文件。取而代之的是，我需要的打开一个新的标签或窗口的，并显示该文件。我怎样才能做到这一点？

When this code is executed, it will ask user to open or save the file. Instead of this I need to open a new tab or window and display the file. How can I achieve this?

注意：

文件将不必要设在网站文件夹。它可能位于一个其他文件夹中。

File won't necessary be located in the website folder. It might be located in an other folder.

推荐答案

，你应该看看的 Htt的presponse.TransmitFile

Response.ContentType = "Application/pdf";
Response.TransmitFile(pathtofile);

如果您希望PDF在新窗口中打开，你将不得不在新窗口中打开下载页面，比如像这样的：

If you want the PDF to open in a new window you would have to open the downloading page in a new window, for example like this:

<a href="viewpdf.aspx" target="_blank">View PDF</a>
