How do I tell DataContractJsonSerializer to not include the “__type” property

Question

I need to add KnownType to the below code for it to serialize successfully. When I do, the generated JSON is as follows:

JSON form of Adult with 1 child: {\"         


        

Answer 1

As I told you in the last question, I don't know, but some research leads me to believe that the following might achieve what you want:

var settings = new DataContractJsonSerializerSettings();
settings.EmitTypeInformation = EmitTypeInformation.Never;

var serializer = new DataContractJsonSerializer(yourType, settings);
