Support of per inheritance level discriminators #60
Description
If i have a 3-level hierarchy and i place a JsonProperty at first and second level
Animal
Dog:Animal
Husky:Dog
Can i deserialize like:
var dog=new Husky();
var data= JsonConvert.SerializeObject<Husky>();
Animal a=JsonConvert.DeserializeObject<Animal>();
So far i get an error and i can only deserialize it like this:
Animal a=JsonConvert.DeserializeObject<Dog>();
P.S My question is better seen here https://stackoverflow.com/questions/54835920/deserializing-with-multiple-levels-of-polymorphic-type-hierarchy
Sample code:
using System;
using Newtonsoft.Json;
using JsonSubTypes;
namespace Test60
{
class Program
{
static void Main(string[] args)
{
Payload run = new Payload.Game.Run();
var data = JsonConvert.SerializeObject(run);
Console.WriteLine(data);
var run2 = JsonConvert.DeserializeObject<Payload>(data);
Console.WriteLine("Hello World!");
}
}
