How to serialize object to json with type info using Newtonsoft.Json?

Question

I want to have a property with type name in JSON when I serialize objects of certain types. I wrote a converter:

public class TypeInfoConverter : JsonConvert         


        

Answer 1

public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) 
    var converters = serializer.Converters.Where(x => !(x is TypeInfoConverter)).ToArray();

    var jObject = JObject.FromObject(value);
    jObject.AddFirst(new JProperty("Type", value.GetType().Name));
    jObject.WriteTo(writer, converters);
}
