public bool TryGetTypeInfo (Type type, out System.Text.Json.Serialization.Metadata.JsonTypeInfo? typeInfo);

member this.TryGetTypeInfo : Type * JsonTypeInfo -> bool

Public Function TryGetTypeInfo (type As Type, ByRef typeInfo As JsonTypeInfo) As Boolean

Parameters

type

Type

The type to resolve contract metadata for.

typeInfo

JsonTypeInfo

When this method returns, contains the resolved contract metadata, or null if the contract could not be resolved.

Returns

Boolean

true if a contract for type was found, or false otherwise.

Exceptions

ArgumentNullException

type is null.

Returned metadata can be downcast to JsonTypeInfo<T> and used with the relevant JsonSerializer overloads.

If the JsonSerializerOptions instance is locked for modification, the method will return a cached instance for the metadata.
