JsonTypeInfoResolver.Combine(IJsonTypeInfoResolver[]) Method

Definition

Namespace:

System.Text.Json.Serialization.Metadata

Assembly:

System.Text.Json.dll

Source:

JsonTypeInfoResolver.cs

Combines multiple IJsonTypeInfoResolver sources into one.

public:
 static System::Text::Json::Serialization::Metadata::IJsonTypeInfoResolver ^ Combine(... cli::array <System::Text::Json::Serialization::Metadata::IJsonTypeInfoResolver ^> ^ resolvers);

public static System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver Combine (params System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver?[] resolvers);

static member Combine : System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver[] -> System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver

Public Function Combine (ParamArray resolvers As IJsonTypeInfoResolver()) As IJsonTypeInfoResolver

Parameters

resolvers

IJsonTypeInfoResolver[]

Sequence of contract resolvers to be queried for metadata.

Returns

IJsonTypeInfoResolver

A IJsonTypeInfoResolver combining results from resolvers.

Exceptions

ArgumentException

resolvers is null.

Remarks

The combined resolver will query each of resolvers in the specified order, returning the first result that is non-null. If all resolvers return null, then the combined resolver will also return null.

Can be used to combine multiple JsonSerializerContext sources, which typically define contract metadata for small subsets of types. It can also be used to fall back to DefaultJsonTypeInfoResolver wherever necessary.
