How to Ignoring Fields and Properties Conditionally During Serialization Using JSON.Net?

by

You can use JSON.NET’s ShouldSerialize-syntax. There’s a good example on JSON.NET site:

http://www.newtonsoft.com/json/help/html/ConditionalProperties.htm

public class Employee
{
    public string Name { get; set; }
    public Employee Manager { get; set; }

    public bool ShouldSerializeManager()
    {
        // don't serialize the Manager property if an employee is their own manager
        return (Manager != this);
    }
}

If ShouldSerialize doesn’t fit your needs, you can take full control of the serialization with the ContractResolvers: http://www.newtonsoft.com/json/help/html/ContractResolver.htm
