Definition

Namespace:
System.Text.Json.Serialization.Metadata
Assembly:

Package:
System.Text.Json v9.0.0-rc.2.24473.5
Package:
System.Text.Json v8.0.5

Overloads

Combine(ReadOnlySpan<IJsonTypeInfoResolver>)

Combines multiple IJsonTypeInfoResolver sources into one.
Combine(IJsonTypeInfoResolver[])

Combines multiple IJsonTypeInfoResolver sources into one.

Combine(ReadOnlySpan<IJsonTypeInfoResolver>)

Combines multiple IJsonTypeInfoResolver sources into one.

public:
 static System::Text::Json::Serialization::Metadata::IJsonTypeInfoResolver ^ Combine(ReadOnlySpan<System::Text::Json::Serialization::Metadata::IJsonTypeInfoResolver ^> resolvers);
public static System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver Combine (scoped ReadOnlySpan<System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver?> resolvers);
static member Combine : ReadOnlySpan<System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver> -> System.Text.Json.Serialization.Metadata.IJsonTypeInfoResolver
Public Function Combine (resolvers As ReadOnlySpan(Of IJsonTypeInfoResolver)) As IJsonTypeInfoResolver

Parameters

resolvers
ReadOnlySpan<IJsonTypeInfoResolver>

Sequence of contract resolvers to be queried for metadata.

Returns

IJsonTypeInfoResolver

A IJsonTypeInfoResolver combining results from resolvers.

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.

Parameters

Sequence of contract resolvers to be queried for metadata.

Returns

Exceptions

ArgumentException

resolvers is null.
