Please take a look at the solution to this StackOverflow issue, it is the one with the Optional<T> struct.

https://stackoverflow.com/questions/12522000/optionally-serialize-a-property-based-on-its-runtime-value

This solution is not ideal because it uses reflection to access values, it also seems like quite a complicated bit of code to do something quite simple.

Could you add a JsonProperty.ShouldSerializeValue that is called with the declaring object and the value of the property about to be serialized?

Or some other solution of your choosing :) I really would like to decide whether or not to serialize a value at runtime without having to write a method for every property.

Given there's already the ability to look for ShouldSerializeXXXX where XXXX is the name for each property, a logical extension might be the ability to define just ShouldSerialize( ) for any class, and have the serialization engine look for such a method (using reflection) on each object being serialized, and call it as necessary to determine whether it should be. It does seem that currently there's no straightforward way of defining custom behaviors for all properties of a given custom class.

Still demanding for this in 2022....
