Solution 1

You can't save files on the client machine, all you can do is write them to the response as you're doing and the client then decides if they want to save the file and if so where to save it.

Like mentioned in Solution 1, you cannot force the client machine to download anything, and the browser won't let your application to do that either. However, instead of "application/pdf" you can set the content type to octet-stream to force the Save File dialog and it will ask the user to save the file.

C#

// I used the following code to download the file directly.
// Works with System.Web namespace being called
@{
    var file = Server.MapPath("~/documents/" + fileName);
    Response.AppendHeader("content-disposition", "attachment; filename=" + fileName);
    Response.ContentType = "application/octet-stream";
    Response.TransmitFile(file);
}

In the above method, I simply tried to pass the file down the stream, you can pass your own file that you just generated perhaps. A good method would be to actually store the file somewhere, and then use that filename (Guid, maybe) and then stream that file down to the users.

Remember: even with this method, user is the king, he has the final decision.

HttpResponse.TransmitFile Method (String) (System.Web)[^]
