JSON.NET - Ignore properties for serialization

I am currently developing a ASP.NET WebAPI using JSON.NET. I am looking to reduce traffic and want to ignore certain properties of my models for serialization, i.e. I don't want to return them in my JSON response, but I want to accept them when they are passed to my endpoint.

Example class

public class User {

    public int Id { get; set; }
    public string Name { get; set; }
    public string Role { get; set; }

}

Use-cases

Problem

When I use the JsonIgnore attribute from JSON.NET, the property is ignored entirely. It is not serialized for my response, but the prop of my User is null, when I post the JSON User to my endpoint.

Is there a way to ignore a prop only for serialization?

Thank you in advance!

Use this and pass null when you want to ignore it!

[JsonProperty("property_name", NullValueHandling=NullValueHandling.Ignore)]

That's exactly what Data Transfer Objects are for. You should create different DTOs for different purposes (GET/POST).
