System.Text.Json.Serialization Namespace

Contains classes that are used to customize and extend serialization and deserialization of objects into JSON formatted documents or streams, either via an attribute model or via type converters.

Classes

JsonAttribute	Provides the base class for serialization attributes.
JsonConstructorAttribute	When placed on a constructor, indicates that the constructor should be used to create instances of the type on deserialization.
JsonConverter	Converts an object or value to or from JSON.
JsonConverter<T>	Converts an object or value to or from JSON.
JsonConverterAttribute	When placed on a property or type, specifies the converter type to use.
JsonConverterFactory	Supports converting several types by using a factory pattern.
JsonDerivedTypeAttribute	When placed on a type declaration, indicates that the specified subtype should be opted into polymorphic serialization.
JsonExtensionDataAttribute	When placed on a property of type IDictionary<TKey,TValue>, any properties that do not have a matching member are added to that dictionary during deserialization and written during serialization.
JsonIgnoreAttribute	Prevents a property from being serialized or deserialized.
JsonIncludeAttribute	Indicates that the member should be included for serialization and deserialization.
JsonNumberEnumConverter<TEnum>	Converter to convert enums to and from numeric values.
JsonNumberHandlingAttribute	When placed on a type, property, or field, indicates what JsonNumberHandling settings should be used when serializing or deserializing numbers.
JsonObjectCreationHandlingAttribute	Determines how deserialization handles object creation for fields or properties.
JsonPolymorphicAttribute	When placed on a type, indicates that the type should be serialized polymorphically.
JsonPropertyNameAttribute	Specifies the property name that is present in the JSON when serializing and deserializing.
JsonPropertyOrderAttribute	Specifies the property order that is present in the JSON when serializing. Lower values are serialized first. If the attribute is not specified, the default value is 0.
JsonRequiredAttribute	Indicates that the annotated member must bind to a JSON property on deserialization.
JsonSerializableAttribute	Instructs the System.Text.Json source generator to generate source code to help optimize performance when serializing and deserializing instances of the specified type and types in its object graph.
JsonSerializerContext	Provides metadata about a set of types that is relevant to JSON serialization.
JsonSourceGenerationOptionsAttribute	Instructs the System.Text.Json source generator to assume the specified options will be used at run time via JsonSerializerOptions.
JsonStringEnumConverter	Converts enumeration values to and from strings.
JsonStringEnumConverter<TEnum>	Converter to convert enums to and from strings.
JsonStringEnumMemberNameAttribute
JsonUnmappedMemberHandlingAttribute	When placed on a type, determines the JsonUnmappedMemberHandling configuration for the specific type, overriding the global UnmappedMemberHandling setting.
ReferenceHandler	Defines how the JsonSerializer deals with references on serialization and deserialization.
ReferenceHandler<T>	Defines how the JsonSerializer deals with references on serialization and deserialization.
ReferenceResolver	Defines how the JsonSerializer deals with references on serialization and deserialization. Defines the core behavior of preserving references on serialization and deserialization.

Interfaces

IJsonOnDeserialized	Specifies that the JSON type should have its OnDeserialized() method called after deserialization occurs.
IJsonOnDeserializing	Specifies that the type should have its OnDeserializing() method called before deserialization occurs.
IJsonOnSerialized	Specifies that the type should have its OnSerialized() method called after serialization occurs.
IJsonOnSerializing	Specifies that the type should have its OnSerializing() method called before serialization occurs.

Enums

JsonIgnoreCondition	Controls how the JsonIgnoreAttribute ignores properties on serialization and deserialization.
JsonKnownNamingPolicy	The JsonNamingPolicy to be used at run time.
JsonNumberHandling	Determines how JsonSerializer handles numbers when serializing and deserializing.
JsonObjectCreationHandling	Determines how deserialization will handle object creation for fields or properties.
JsonSourceGenerationMode	The generation mode for the System.Text.Json source generator.
JsonUnknownDerivedTypeHandling	Defines how objects of a derived runtime type that has not been explicitly declared for polymorphic serialization should be handled.
JsonUnknownTypeHandling	Defines how deserializing a type declared as an Object is handled during deserialization.
JsonUnmappedMemberHandling	Determines how JsonSerializer handles JSON properties that cannot be mapped to a specific .NET member when deserializing object types.
