The System.Json namespace provides standards-based support for the serialization of JavaScript Object Notation (JSON).
JSON is a lightweight, text-based data interchange format that is used to serialize structured data for transmission over networks. It has three primitive data types: string, number, and Boolean. It has two data structures: array and object. An array is an ordered collection of values, where the value can be a JSON primitive, object or array. An object is an unordered set of key/value pairs. The key is a string and the value, as with the array, can be a JSON primitive, object, or array.
In this documentation, the serialized textual representation of JSON is referred to as “text-based JSON” to distinguish it from the deserialized representation of JSON as a Common Language Runtime (CLR) type, which is referred to here as a “JSON CLR type” or as a “JSON CLR object” if we are referring to an instance of the type.
JSON CLR types represent the three text-based JSON primitives with the JsonPrimitive type. The JsonType()()() property indicates which primitive is contained in the type instance: String, Number, or Boolean.
JSON CLR types represent the two text-based structured types with JsonArray and JsonObject. A JsonArray is an ordered sequence of zero or more JsonValue objects. A JsonValue is the JSON CLR representation of a JSON text-based value, which can be either a primitive or structured type. A JsonObject is an unordered collection of zero or more String/JsonValue pairs, which represent the key/value pairs of the text-based JSON object.
