public abstract class SystemTextJsonSerializer : IExtendedTypeSerializer, IProjectableTypeDeserializer, IStreamingTypeDeserializer, IBufferedTypeSerializer, ITypeSerializer

Remarks

This class is currently experimental and subject to change. It does not support all serialization features supported by the DefaultSerializer. Known limitations currently include:

Couchbase.Transactions is not currently supported.
No support for dynamic types.
Some properties of QueryMetaData which use dynamic, such as Profile and Signature, are not populated.
View-style queries are not supported using JsonSerializerContext, only reflection-based serialization.
Any use of Newtonsoft.Json.Linq.JToken should be replaced with JsonElement or object.

Options

JsonSerializerOptions used for serialization and deserialization.

Declaration

public abstract JsonSerializerOptions Options { get; }

Property Value

Type	Description
JsonSerializerOptions

CanSerialize(Type)

Determines if the serializer can serialize and deserialize the specified type.

Create(bool)

Create a new SystemTextJsonSerializer with default options, optionally enabling increased Newtonsoft.Json compatibility.

Declaration

public static SystemTextJsonSerializer Create(bool increasedNewtonsoftCompatibility = false)

Parameters

Type	Name	Description
bool	increasedNewtonsoftCompatibility	Enable increased Newtonsoft.Json compatibility.

Returns

Type	Description
SystemTextJsonSerializer	A new SystemTextJsonSerializer.

Remarks

The increasedNewtonsoftCompatibility parameter doesn't make this fully compatible with Newtonsoft.Json. However, it does enable several features to make it more compatible such as case-insensitive property name deserialization, ignoring comments and trailing commas, serializing public fields, etc. For details on compatibility, see https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-migrate-from-newtonsoft-how-to

Create(JsonSerializerOptions)

Create a new SystemTextJsonSerializer with supplied JsonSerializerOptions.

Declaration

public static SystemTextJsonSerializer Create(JsonSerializerOptions options)

Parameters

Type	Name	Description
JsonSerializerOptions	options	JsonSerializerOptions to control serialization and deserialization.

Returns

Type	Description
SystemTextJsonSerializer	A new SystemTextJsonSerializer.

Create(JsonSerializerContext)

Create a new SystemTextJsonSerializer using a supplied JsonSerializerContext.

Declaration

public static SystemTextJsonSerializer Create(JsonSerializerContext context)

Parameters

Type	Name	Description
JsonSerializerContext	context	JsonSerializerOptions to use for serialization and deserialization.

Returns

Type	Description
SystemTextJsonSerializer	A new SystemTextJsonSerializer.

Remarks

This overload should be used to supply custom serializers on a per-request basis that are optimized for the particular type being serialized or deserialized. Any type which isn't registered in the JsonSerializerContext will be handled using the Options.
