Can I optionally turn off the JsonIgnore attribute at runtime?

Question

I am creating a JSON file with Newtonsoft.Json from a set of classes. The file created is very large, so I have created JsonProperty\'s for the properties to re

Answer 1

Json support us to ignore property that don't want return. Example

class Foo
{
    public int Id { get; set; }
    public string Name { get; set; }
    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    public string AlternateName { get; set; }    
}

How to use it:

Foo foo = new Foo
{
    Id = 1,
    Name = "Thing 1",
    AlternateName = null,   
};

string json = JsonConvert.SerializeObject(foo);
