Can I instruct Json.NET to deserialize, but not serialize, specific properties? [duplicate]

Question

I have an AngularJS + MVC 5 + Web API 2 app that allows users to manage collections of objects in the browser and commit all changes at once when a Save button is clicked. As changes are made, one or more properties are added to the JavaScript objects: IsAdded, IsUpdated, IsRemoved. The properties are checked server-side to determine what to do when persisting the model.

The model is served up using Json.NET via Web API, and the base class is:

public class CollectionItemViewModel : ICollectionItem
{
    public bool IsAdded { get; set; }
    public bool IsUpdated { get; set; }
    public bool IsRemoved { get; set; }
}

This works great, but adds cruft to my serialized JSON. I can choose to not serialize these three properties with ShouldSerialize, but that also prevents them from deserializing.

public bool ShouldSerializeIsAdded()
{
    return false;
}

public bool ShouldSerializeIsUpdated()
{
    return false;
}

public bool ShouldSerializeIsRemoved()
{
    return false;
}

Is it possible to deserialize, but not serialize, specific properties using Json.NET?

Answer 1

You should be able to just use the ShouldSerialize* methods as shown in the question. These only impact serialization, not deserialization.
