        {
            var files = Request.Form.Files;
            long size = files.Sum(f => f.Length);
            foreach (var file in files)
                if (file.Length > 0)
                    using (var stream = new MemoryStream())
                    {
                        await file.CopyToAsync(stream);
                        db.AttachmentItems.Add(new AttachmentItem
                        {
                            FileName = file.FileName,
                            Body = stream.ToArray()
                        });
                    }
            await db.SaveChangesAsync();
            return Ok(new { count = files.Count, size });
        }
