JsonSubTypes does not work with JsonSerializer in namespace. In Asp.net core 3.1, the default Json serializer is JsonSerializer in namespace. So please make sure the framework is using Newtonsoft.Json to serialize/deserialize JSON data. Note: JsonSubTypes depends on Newtonsoft.Json to work. : This attribute creates a map between the Dog class and the “Dog” value in PetType property, i.e., if the PetType property value is “Dog”, framework will try to deserialize the JSON string to Dog object.It supports JSON serialization, JSON deserialization, MessagePack, streams. : This attribute creates a map between the Cat class and the “Cat” value in PetType property, i.e., if the PetType property value is “Cat”, framework will try to deserialize the JSON string to Cat object. ArduinoJson is a JSON library for Arduino, IoT, and any embedded C++ project.: This attribute tell the framework the JsonSubtypes is based on the property called “PetType”.The following 3 attributes are applied to the BasePet class: You can find the detailed document about JsonSubTypes in Github: yaml format.īehind the scene, the Swagger Editor uses JsonSubTypes attribute to decorate the BasePet class.
In the sub class definition, we would put the reference to the base type first followed by the new properties in the sub class. This keyword validates the value against all the subschemas. The inheritance is achieved in JSON by the keyword allOf. How do we define the JSON schema and C# class (auto generated from the JSON schema) to achieve this? Inheritance in JSON: allOf However, during the run time, the Pet property may be a Cat or Dog. The Person class has a property called Pet, which is defined as BasePet type. prettyPrint: Type: Boolean: Determines whether the JSON generator creates. Supports JSON Schema Draft 3, Draft 4, Draft 6, Draft 7 and Draft 2019-09. Let’s make an example, we have a Person class, an abstract BasePet class (base class), a Cat class (inherited from BasePet class) and a Dog class (inherited from BasePet class). JSON class to perform round-trip JSON serialization and deserialization of. An online, interactive JSON Schema validator.
#Json class generator json.net how to
However, if the C# object has class inheritance structure and polymorphism, it would be much tricky how to define the JSON schema. Instructions to convert JSON object to C code Paste the JSON string in the input field and click on Generate C Classes button. These JSON data would be deserialized to C# object. The easiest way to do this is to use NuGet launch NuGet, search for Json. In C# web API, we use JSON to pass the data back and forth. Class inheritance and polymorphism in JSON schema
