Question

I have a sql database that stores some documents.

A user can sign into the application, and view a list of their documents.

When clicking a linkbutton download in a gridview of their docs, I get the file from the database, write it to the file system, and then execute this code.

    System.IO.FileInfo file = new System.IO.FileInfo(System.Configuration.ConfigurationManager.AppSettings['UploadPath'] + DocumentName);      Response.Clear();     Response.ClearContent();     Response.ClearHeaders();     Response.Cookies.Clear();     Response.Cache.SetCacheability(HttpCacheability.Private);     Response.CacheControl = 'private';     Response.Charset = System.Text.UTF8Encoding.UTF8.WebName;     Response.ContentEncoding = System.Text.UTF8Encoding.UTF8;     Response.AppendHeader('Content-Length', file.Length.ToString());     Response.AppendHeader('Pragma','cache');     Response.AppendHeader('Expires', '60');     Response.ContentType = GetContentType(file.Extension);     Response.AppendHeader('Content-Disposition',     'inline; ' +     'filename=\'' + file.Name + '\'; ' +     'size=' + file.Length.ToString() + '; ' +     'creation-date=' + DateTime.Now.ToString('R') + '; ' +     'modification-date=' + DateTime.Now.ToString('R') + '; ' +     'read-date=' + DateTime.Now.ToString('R')); 

My GetContentType() method just returns the appropriate file type for the files I’m allowing ‘application/pdf, application/msw0rd, etc.

My problem is that when the file gets saved, it’s the webpage itself, not the file from the file system. And in google chrome, it’s putting a .htm extension on the end of the filename, I guess because it knows it’s a web page?

Anyhow, a great first step would be to get the actual file, and not a copy of the web page in HTML they are sitting on!

Thanks.

Answer 1

How are you sending the actual content of the file??

I usually use Response.TransmitFile method, it basically opens the file and sends its content to the Response.OutputStream
