DTO Deserialization - STARIONGROUP/COMET-SDK-Community-Edition GitHub Wiki

The CDP4JsonSerializer supports the deserialization of a C# object and is performance optimized for DTO objects and the Classless-DTO. The following snippet demonstrates how to deserialize a JSON Stream to an IEnumerable<Thing>.

// assume a json stream is coming from a web resource
var metadataprovider = new MetaDataProvider();
var serializer = new Cdp4JsonSerializer(this.metadataprovider, new Version(1, 1, 0));
var dtos = serializer.Deserialize(stream);

The system.text.json library provides means to customize and control how objects are deserialized.

The ThingSerializer derives from JsonConverter<T>. The Read method and and CanConvert are overriden to deserialize to a DTO. The static DtoFactory implements the ToDto extension method that converts a JsonElement to a DTO using the any of the *Resolver static classes.

The ClasslessDtoSerializer derives from JsonConverter<T>. The Read method and and CanConvert are overriden to deserialize to a Classless-DTO.
