Downloading files using ASP.NET .ashx modules

问题

I have ASP.NET page with an iframe on it for displaying some pdf reports on this page. When user select the report type from dropdown, I add the needed for report data into the ASP.NET Session and change the attribute "src" of the iframe to .ashx module address which generates the .pdf report. But if Adobe glug-in for viewing .pdf files in browser is not installed, browser proposes to save report file and name of the proposed file is "HandlerName.ashx". But I want to make the browser proposed to save the file with the name "Report.pdf". Can I do this? Are there any workarounds?

回答1:

Try inline content-disposition, however I have to check this:

Response.ContentType = "application/pdf"; 
Response.AppendHeader("content-disposition", "inline; filename=" + name ); 

回答2:

Add the following header in your ashx-file:

context.Response.AddHeader("content-disposition", "attachment;filename=PUTYOURFILENAMEHERE.pdf");
context.Response.ContentType = "application/pdf";

回答3:

Use     


 Response.Clear();
 Response.ContentType = "application/octet-stream";
 Response.AddHeader("Content-Disposition", "attachment; filename=Report.PDF");                                            
 Response.WriteFile(Server.MapPath("~/YourPath/Report.PDF"));
 Response.End();
