I have a situation where the JSON
returned from a REST
-service returns a list of Movie-objects, all specced out with a ton of information. A couple
Ok, I did it for fun, but don't think is useful or the best way, anyway...
Declaring the "dynamic" attributes as object and then create methods to obtain the properties as something like ImagesAsList or ImagesAsString. I did it with Extension Methods.....
var movies = JsonConvert.DeserializeObject>(str);
Class
class Movie
{
[JsonProperty("title")]
public string Title { get; set; }
[JsonProperty("images")]
public object Images { get; set; }
[JsonProperty("actors")]
public object Actor { get; set; }
[JsonProperty("directors")]
public object Directors { get; set; }
}
Extension Methods
static class MovieExtension
{
public static List ImagesAsList(this Movie m)
{
var jArray = (m.Images as JArray);
if (jArray == null) return null;
return jArray.Select(x => x.ToString()).ToList();
}
public static string ImagesAsString(this Movie m)
{
return m.Images as string;
}
}
EDIT
After reading @yamen comments I did some changes like:
var settings = new JsonSerializerSettings();
settings.Converters.Add(new MoviesConverter());
var movies = JsonConvert.DeserializeObject>(str, settings);
Class
class Movie
{
[JsonProperty("title")]
public List Title { get; set; }
[JsonProperty("images")]
public List Images { get; set; }
[JsonProperty("actors")]
public List Actor { get; set; }
[JsonProperty("directors")]
public List Directors { get; set; }
}
Converter
class MoviesConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return (objectType == typeof(string)) || (objectType == typeof(List)) ;
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.StartArray)
{
var l = new List();
reader.Read();
while (reader.TokenType != JsonToken.EndArray)
{
l.Add(reader.Value as string);
reader.Read();
}
return l;
}
else
{
return new List { reader.Value as string };
}
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
//ToDo here we can decide to write the json as
//if only has one attribute output as string if it has more output as list
}
}
