Constructors

DerivedTypeJsonConverter(IDerivedTypes)

Represents a JsonConverter<T> for converting types that are adorned with the DerivedTypeAttribute.

public DerivedTypeJsonConverter(IDerivedTypes derivedTypes)

Parameters

derivedTypes IDerivedTypes: IDerivedTypes to use for discovering correct type.

Remarks

Initializes a new instance of the DerivedTypeJsonConverter<T> class.

Fields

DerivedTypeIdProperty

The property used in JSON to identify the derived type id.

public const string DerivedTypeIdProperty = "_derivedTypeId"

Field Value

string

Methods

Read(ref Utf8JsonReader, Type, JsonSerializerOptions)

[UnconditionalSuppressMessage("Trimming", "IL2026", Justification = "Derived type JSON deserialization uses types registered at startup that are preserved.")]
[UnconditionalSuppressMessage("AOT", "IL3050", Justification = "Derived type JSON deserialization uses types registered at startup that are safe for AOT.")]
public override T? Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)

Parameters

reader Utf8JsonReader
typeToConvert Type
options JsonSerializerOptions

Returns

T

Remarks

A missing derived type identifier returns the default value so payloads written without nested identifiers by earlier versions remain readable when replaying persisted events.

Write(Utf8JsonWriter, T, JsonSerializerOptions)

[UnconditionalSuppressMessage("Trimming", "IL2026", Justification = "Derived type JSON serialization uses types registered at startup that are preserved.")]
[UnconditionalSuppressMessage("Trimming", "IL2075", Justification = "Derived type JSON serialization accesses well-known type properties that are preserved.")]
[UnconditionalSuppressMessage("AOT", "IL3050", Justification = "Derived type JSON serialization uses types registered at startup that are safe for AOT.")]
public override void Write(Utf8JsonWriter writer, T value, JsonSerializerOptions options)

Parameters

writer Utf8JsonWriter
value T
options JsonSerializerOptions

Remarks

Nested children and collections declared with a derived type family use their declared types to preserve type identifiers and the converter's naming rules. Other properties use runtime types.
