My class has a property 'PropertyA', I want this to appear as 'PropertyB' in a JSON object when it's serialized. Is there any sort of attribute I can use?

3Which JSON serializer are you using? JavaScriptSerializer? JSON.NET? DataContractJsonSerializer? ...? – Marc Gravell Sep 17 '12 at 09:05

Sorry, should've gave more details - DataContractJsonSerializer is what I'm using. Thanks. – Sep 17 '12 at 09:06

For Json.NET and DataContractJsonSerializer use DataMemberAttribute:
[DataMember(Name="PropertyB")]
T PropertyA { ... }
Make sure that your class is decorated with the [DataContract] attribute as well.
If you're using JavaScriptSerializer, you need to create derived implementation, as described here: JavaScriptSerializer.Deserialize - how to change field names

and if I do not have access to change the DataMenber property? can I add a translator or something like that at serializing time? – rolivares Oct 30 '13 at 12:35

3Also don't forget to add `[DataContract]` on top of the class – Hossein Narimani Rad Aug 25 '17 at 04:01

[DataContract] was what I needed as well. Thanks @HosseinNarimaniRad ! – Mason11987 Feb 13 '18 at 19:28

ATTENTION! Adding `[DataContract]` does change the serialization logic. Without it all properties will be serialized, after decorating the class with it only properties decorated with `DataMemberAttribute` will be serialized/deserialized. – Rekshino Jul 05 '21 at 17:48
