Following is a snippet required to download a file


    private void StartDownloadFile(string attachmentPath)
        {
            FileInfo file = new FileInfo(attachmentPath);
            Response.Clear();
            Response.ClearHeaders();
            Response.ClearContent();
            Response.AppendHeader("Content-Disposition", "attachment; filename = " + file.Name);
            Response.AppendHeader("Content-Length", file.Length.ToString());
            Response.ContentType = "application/download";
            Response.WriteFile(file.FullName);
            Response.Flush();
            Response.Close();
            Response.End();
        }
