Deserialize JSON to Dictionary

Question

I want to deserialize a Json to the following class

public class Config
{
    public String Name { get; set; }
    public SSOType Type { get; set; }
    public Dictionary<String, String> Configuration { get; set; }
}

Hence, two properties would be deserialized "as usual", and the rest would be pushed into the dictionary.

JsonConvert.DeserializeObject<Config>(filetext);

This pushs datas to properties Name and Type, but the dictionary stays empty ...

I guess the json shall look like

{
    "name":"something",
    "type":"something",
    "configuration":{
        "thing1":"value",
        "thing2":"value",
        "thing3":"value"
            }
}

but I'd like the json to be like

{
    "name":"something",
    "type":"something",
    "thing1":"value",
    "thing2":"value",
    "thing3":"value"
}

How to tweak the deserialization so it works ?

Would this work?

public class Config : Dictionary<string, string>
{
    public String Name { get; set; }
    public SSOType Type { get; set; }
}

Properties will be ignored, iirc. – Athari Oct 22 '14 at 16:49
Yeah, you're right. Looks like this is a way to make those properties be included - http://stackoverflow.com/a/14894945/906690 – peaceoutside Oct 22 '14 at 17:07

Your options:

JsonExtensionDataAttribute on a dictionary which will get all data for which properties are not found, and OnDesrialized callback to convert the dictionary to the format you need:

public class Config
{
    public String Name { get; set; }

    [JsonIgnore]
    public Dictionary<string, string> Configuation { get; set; }

    [JsonExtensionData]
    private Dictionary<string, JToken> _configuration;

    [OnDeserialized]
    private void Deserialized (StreamingContext context)
    {
        Configuation = _configuration.ToDictionary(i => i.Key, i => (string)i.Value);
    }
}

Custom JsonConverter which will read JSON DOM and convert it to your class. You can find many examples on StackOverflow.
