public abstract class SystemTextJsonSerializer : IExtendedTypeSerializer, IProjectableTypeDeserializer, IStreamingTypeDeserializer, 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.

Methods

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.
