Deserialize read-only variables

Question

I have class like this:

public class Pussy {
    public readonly int Meows;

    [JsonConstructor]
    private Pussy() { }

    public Pussy(int meows)
    {
        this.Meows = meows;
    }
}

When I'm trying to serialize it with Json.NET, it working fine:

{"Meows":3}

But when deserialize, it's just creating class with Meows set to 0.

What's wrong? How to fix it?

Answer 1

Try to use JsonProperty attribute for readonly fields

[JsonProperty]
public readonly int Meows;

Or JsonConstructor attribute for non-default ctor.

[JsonConstructor]
public Pussy(int meows)
