Question

从电子邮件中的链接点击时，以下代码会导致PDF文档在浏览器中打开：

Response.ContentType = mime;
Response.WriteFile(path);
HttpContext.Current.ApplicationInstance.CompleteRequest();

有没有办法强制客户端在Adobe Acrobat / reader中本地打开它？

Answer 1

客户端的行为方式取决于几个方面，包括客户端设置......你可以试试这个

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment; filename="+filePath); 
Response.WriteFile(path);
HttpContext.Current.ApplicationInstance.CompleteRequest();

Answer 2

Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition","attachment; filename=SailBig.pdf");
Response.TransmitFile( Server.MapPath("~/images/sailbig.pdf") );
Response.End();

Answer 3

您可以做的最好的事情是添加内容处置标头。这将导致出现下载文件对话框。

Response.AddHeader("content-disposition", "attachment;filename=xxx.pdf");

在Adobe Reader中打开PDF，而不是在浏览器中打开
