Now we are going to see how to download a file or image from the Server folder ie: showing file/open dialog box. For this we have to use Response object to show or get the file.

        private void WriteFileToResponse()
        {
            Response.Clear();
            Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.MapPath("~/Download/" + FileName));
            //                    Response.AddHeader("Content-Length", file.Length.ToString());
            Response.ContentType = "application/octet-stream";

            //Write the file to the Response Output stream without buffering. 
            //This is new to ASP.NET 2.0. Prior to that use WriteFile. 
            Response.TransmitFile(Server.MapPath("~/Download/" + FileName));
            Response.Flush();
            Response.End();
        }
