I am quite familiar with C# but new to JSON. I cannot figure out how to parse the data returned by the API.

First I tried this...

        string url = "https://api.themoviedb.org/3/movie/tt1872181?api_key=" + API_KEY;

        var request = System.Net.WebRequest.Create(url) as System.Net.HttpWebRequest;
        request.KeepAlive = true;
        request.Method = "GET";
        request.Accept = "application/json";
        request.ContentLength = 0;

        string responseContent = null;

        WebResponse response = request.GetResponse();
        //StreamReader reader = new StreamReader(response.GetResponseStream());

        StreamReader stream = new StreamReader(url);
        string text = stream.ReadToEnd();

And I DID receive the data from the API in JSON format. I could parse this data the 'old fashion' way but I know that isn't the correct way to do it nor is it efficient. So, in an effort to parse the JSON data the correct way, I changed my script to this...

        // Creates an HttpWebRequest with the specified URL. 
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        // Send the request and wait for response.          
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        // Get the response stream
        Stream responseStream = response.GetResponseStream();
        DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(movie));

        object objResponse = (movie)jsonSerializer.ReadObject(responseStream);

        movie jsonResponse = objResponse as movie;

        response.Close();

Which seems to work. The error I am getting, I believe, has to do with the MOVIE class. The error I am getting is this.

An unhandled exception of type 'System.Runtime.Serialization.InvalidDataContractException' occurred in System.Runtime.Serialization.dll

Additional information: Type 'emma.movie' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.

And, finally, here is my movie class:

class movie
{
    public int Id { get; set; }
    public string ImdbId { get; set; }
    public string Title { get; set; }
    public string OriginalTitle { get; set; }
    public string Status { get; set; }
    public string Tagline { get; set; }
    public string Overview { get; set; }
    public string Homepage { get; set; }

    public string BackdropPath { get; set; }
    public string PosterPath { get; set; }

    public bool Adult { get; set; }

    public List<string> BelongsToCollection { get; set; }
    public List<string> Genres { get; set; }

    public DateTime ReleaseDate { get; set; }
    public long Revenue { get; set; }
    public long Budget { get; set; }
    public int Runtime { get; set; }

    public double Popularity { get; set; }
    public double VoteAverage { get; set; }
    public int VoteCount { get; set; }

    public List<string> ProductionCompanies { get; set; }
    public List<string> ProductionCountries { get; set; }
    public List<string> SpokenLanguages { get; set; }

    public string AlternativeTitles { get; set; }
    public string Releases { get; set; }
    public string Casts { get; set; }
    public string Images { get; set; }
    public string Keywords { get; set; }
    public string Trailers { get; set; }
    public string Translations { get; set; }
    public string SimilarMovies { get; set; }
    public string SearchContainer { get; set; }
    public List<string> Changes { get; set; }

}

Any help you can provide is greatly appreciated.
