Question

I have an existing class in an external assembly which I can’t change.
I would like to serialize an object from this class with Newtonsoft JSON.Net, but not all the properties.

Normally I can do this with the JsonIgnoreAttribute attribute like this:

public class TestJsonClass
{
    public string PropA { get; set; }

    [JsonIgnoreAttribute]
    public string PropB { get; set; }
}

But since I can’t change the class, is there a way to ignore a property without attributes?

Answer 1

Try inherit class and override property with appropriate annotations or copy property values in a completely new class.
