You are developing an application. The application converts a Location object to a string by using a
method named WriteObject. The WriteObject() method accepts two parameters, a Location object
and an XmlObjectSerializer object.
The application includes the following code. (Line numbers are included for reference only.)

You need to serialize the Location object as a JSON object.
Which code segment should you insert at line 20?

A.
New DataContractSerializer(typeof(Location))

B.
New XmlSerializer(typeof(Location))

C.
New NetDataContractSenalizer()

D.
New DataContractJsonSerializer(typeof(Location))

Explanation:
The DataContractJsonSerializer class serializes objects to the JavaScript Object Notation (JSON) and
deserializes JSON data to objects.
Use the DataContractJsonSerializer class to serialize instances of a type into a JSON document and to
deserialize a JSON document into an instance of a type.
