How to exclude property from Json Serialization

Question

I have a DTO class which I Serialize

Json.Serialize(MyClass) 

How can I exclude a public property of it?

(It has to be public, as I use it in my code somewhere else)

Answer 1

If you are using Json.Net attribute [JsonIgnore] will simply ignore the field/property while serializing or deserialising.

public class Car {   // included in JSON   public string Model { get; set; }   public DateTime Year { get; set; }   public List<string> Features { get; set; }    // ignored   [JsonIgnore]   public DateTime LastModified { get; set; } } 

Or you can use DataContract and DataMember attribute to selectively serialize/deserialize properties/fields.

[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; } }
