Is there something like the opposite of a JsonIgnore?

Question

The JsonIgnore attribute can be used to ignore certain properties in serialization. I was wondering if it is possible to do the opposite of that? So a JsonSeria

Answer 1

An alternative to MemberSerialization.OptIn is using DataContract/DataMember attributes:

[DataContract]
public class Computer
{
  // included in JSON
  [DataMember]
  public string Name { get; set; }
  [DataMember]
  public decimal SalePrice { get; set; }

  // ignored
  public string Manufacture { get; set; }
  public int StockCount { get; set; }
  public decimal WholeSalePrice { get; set; }
  public DateTime NextShipmentDate { get; set; }
}
