Hello Mike,

thx fort he code, but thats are basics and I already know.

What i need is, if I have for exaple the PosterPath form yor example:

With this code

Uri imageUri = client.GetImageUrl(size, imageData.FilePath);

I get

http://image.tmdb.org/t/p/w300/uhYoytlNaq46dG81wLmHqaSuzWu.jpg

what I need ist to get this specific Image so I can convert it to an bytearry to store it in a database or Bitmapsource to display it on a screen or…

I hope i can explain what i mean?

Wolfgang

Oh - but once you have the URL, can't you download it with an HttpClient?

I could add a method to fetch it...

[WolfgangRoggen]

Surely, but I’m thinking it should be a a part of your wrapper to make it complete.

Otherwise it needs a 2nd HttpClient and you have already one.

I’ve checked it and i made a solution. But I‘m no expert in http programming. So could be there is a better solution:

   public async Task<byte[]> GetImageByPathAsync(string path, string imageSize)

    {

        if (string.IsNullOrWhiteSpace(path))

        {

            return null;

        }

        try

        {

            Uri uri = GetImageUrl(imageSize, path);

            string url = uri.ToString();

            // _client = TMDbClient

            RestRequest req = _client.Create(url);

            var resp = await req.ExecuteGet(CancellationToken.None).ConfigureAwait(false);

            using (Stream stream = await resp.GetContent().ConfigureAwait(false))

            {

                Image image = Image.FromStream(stream);

                ImageConverter imageConverter = new ImageConverter();

                //the conversion is needed, because the image exists only as long the stream is alive

                byte[] array = (byte[])imageConverter.ConvertTo(image, typeof(byte[]));

                return array;

            }

        }

        catch (Exception e)

        {

            Console.WriteLine(e);

            throw;

        }

    }

And in private async Task SendInternal(HttpMethod method, CancellationToken cancellationToken)

you have ta add

               switch (resp.StatusCode)

                {

                     // if we have no Json, e. g. from GetImageByPathAsync(…)

                    case (HttpStatusCode.OK):

                        return resp;

I've added a function to download the images. Let me know if it works out for you :).
