Download file to local dir

Hello! I try to Download to disc one file from cloud. I use Dropbox .Net SDK C#. Here my code :

static async Task Download(string folder, string file)
        {
            var dbx = new DropboxClient("TOKEN");
            using (var response = await dbx.Files.DownloadAsync(folder + "/" + file))
            {
                if (response != null)
                    Console.WriteLine("Download start - {0}", response.Response.Name);
                else
                {
                    Console.WriteLine("file not found");
                }

                var files = await response.GetContentAsStreamAsync();
                using (FileStream fileStream = File.Create(response.Response.Name, (int)files.Length))
                {
                    byte[] data = new byte[files.Length];
                    files.Read(data, 0, (int)data.Length);
                    fileStream.Write(data, 0, data.Length);
                }
                Console.WriteLine("file was Downloaded");
            }
        }

I have `Download start ` but never get `file was Downloaded`, why ?
