ValueSerializer.TypeReferences(Object, IValueSerializerContext) Method

Definition

Namespace:

System.Windows.Markup

Assembly:

System.Xaml.dll

Gets an enumeration of the types referenced by the ValueSerializer.

public:
 virtual System::Collections::Generic::IEnumerable<Type ^> ^ TypeReferences(System::Object ^ value, System::Windows::Markup::IValueSerializerContext ^ context);

public virtual System.Collections.Generic.IEnumerable<Type> TypeReferences (object value, System.Windows.Markup.IValueSerializerContext context);

abstract member TypeReferences : obj * System.Windows.Markup.IValueSerializerContext -> seq<Type>
override this.TypeReferences : obj * System.Windows.Markup.IValueSerializerContext -> seq<Type>

Public Overridable Function TypeReferences (value As Object, context As IValueSerializerContext) As IEnumerable(Of Type)

Parameters

value

Object

The value being serialized.

context

IValueSerializerContext

Context information that is used for conversion.

Returns

IEnumerable<Type>

The types converted by this serializer.

Remarks

Any types a ValueSerializer converts should be included in the returned enumeration. This allows a serializer to ensure a de-serializer has enough information about the types this serializer converts.

Overriding this method is an advanced scenario. Overriding should only be necessary if you are implementing a system where CLR type system ownertype-property relationships available to a XAML schema context do not report enough information.

WPF Usage Notes

The WPF property system implements an internal value serializer that overrides TypeReferences because a dependency property has a concept that it can have added owners. WPF expressions also have special internal handling.
