Can you post your Movie class and the JSON returned by the TMDb API?

Here is my Movie class:

public 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 BelongsToCollection { get; set; }
        public List 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 ProductionCompanies { get; set; }
        public List ProductionCountries { get; set; }
        public List SpokenLanguages { get; set; }

        public AlternativeTitles AlternativeTitles { get; set; }
        public Releases Releases { get; set; }
        public Casts Casts { get; set; }
        public Images Images { get; set; }
        public KeywordsContainer Keywords { get; set; }
        public Trailers Trailers { get; set; }
        public TranslationsContainer Translations { get; set; }
        public SearchContainer SimilarMovies { get; set; }
        public SearchContainer Lists { get; set; }
        public List Changes { get; set; }

    }

From apiary.io ... Response Body:

{"adult" : false , "backdrop_path" : "/22DQWwjaam1LHTAEapxO2Wg7s2H.jpg" , "belongs_to_collection" : { "id" : 1570 , "name" : "Die Hard Collection" , "poster_path" : "/9RzaUN5E0S6UbXlEVrotKUSMX75.jpg" , "backdrop_path" : "/5kHVblr87FUScuab1PVSsK692IL.jpg" } , "budget" : 92000000 , "genres" : [ { "id" : 28 , "name" : "Action" } , { "id" : 53 , "name" : "Thriller" } ] , "homepage" : "" , "id" : 47964 , "imdb_id" : "tt1606378" , "original_title" : "A Good Day to Die Hard" , "overview" : "Iconoclastic, take-no-prisoners cop John McClane, for the first time, finds himself on foreign soil after traveling to Moscow to help his wayward son Jack - unaware that Jack is really a highly-trained CIA operative out to stop a nuclear weapons heist. With the Russian underworld in pursuit, and battling a countdown to war, the two McClanes discover that their opposing methods make them unstoppable heroes." , "popularity" : 29.1271371554015 , "poster_path" : "/7JKli6FqxK6kEsNRUW8JVGmGSNI.jpg" , "production_companies" : [ { "name" : "20th Century Fox" , "id" : 25 } ] , "production_countries" : [ { "iso_3166_1" : "US" , "name" : "United States of America" } ] , "release_date" : "2013-02-14" , "revenue" : 303725075 , "runtime" : 97 , "spoken_languages" : [ { "iso_639_1" : "en" , "name" : "English" } , { "iso_639_1" : "ru" , "name" : "Pусский" } ] , "status" : "Released" , "tagline" : "Yippee Ki-Yay Mother Russia" , "title" : "A Good Day to Die Hard" , "vote_average" : 5.2 , "vote_count" : 701 }

So for example the "backdrop_path" is giving me "/22DQWwjaam1LHTAEapxO2Wg7s2H.jpg" from apiary.io, but when I deserialize the object with JSON.net it is showing null for that.... as well as a bunch of others.

Thanks!!!

Json.Net uses attributes to serialize/deserialize JSON. Try adding a JsonPropertyAttribute to your properties. This should look something like this:

public class TmdbMovie 
    {
        [JsonProperty( PropertyName = "adult" )]
        public Boolean IsAdult { get; set; }

        [JsonProperty( PropertyName = "backdrop_path" )]
        public String BackdropPath { get; set; }

        [JsonProperty( PropertyName = "belongs_to_collection" )]
        public TmdbBelongsToColelction 

        [JsonProperty( PropertyName = "budget" )]
        public Int64 Budget { get; set; }
}

That makes perfect sense. I've made all the changes, but am now having the following error. I appreciate your help! I'm not sure what to do at this point.

Error: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[TMDbLib.Objects.Movies.BelongsToCollection]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

Path 'belongs_to_collection.id', line 1, position 96.

Here is the BelongsToCollection Class:

    public class BelongsToCollection
    {
        [JsonProperty(PropertyName = "id")]
        public int Id { get; set; }
        [JsonProperty(PropertyName = "name")]
        public string Name { get; set; }
        [JsonProperty(PropertyName = "poster_path")]
        public string PosterPath { get; set; }
        [JsonProperty(PropertyName = "backdrop_path")]
        public string BackdropPath { get; set; }
    }

Well if I understand this correctly, Json.Net throws an error because of it is not able to deserialize the JSON into the specified Type.
As far as I can see, the Problem is that you are trying to deserialize a non-array JSON value into a collection (e.g. List).

Are you sure that Json.Net throws the exception while deserializing BelongsToCollection? Can you post the JSON again?

Btw. This may be useful for you http://json2csharp.com/ (Generates c# classes based on a JSON)

Thanks. I'll look at that website. The reason I thought it had something to do with BelongsToCollection was the last line of the error: "Path 'belongstocollection.id', line 1, position 96." I guess even if I fix that, it may find other problems.

Those error messages are almost always correct… but they are often tricky to understand.

I guess that you have a BelongsToCollection property in your movie class, right?

Is this property of type List or some sort of collection/array?

If yes… you should change the type to just BelongsToCollection (none-collection).

If you post the JSON which you are trying to deserialize, I can maybe give you a more helpful answer.

Alright, I think I've got it fixed, but I'm not sure why :) .... I've removed all of the "[JsonProperty( PropertyName = ... )] lines and have renamed all of the field names (hopefully I've got my programming lingo correct) to match the naming convention of the JSON that is being returned. That seems to map everything properly and I'm not getting any error messages. So for now, I'll say that this has been fixed.
