ComposablePart.Metadata Property

Gets the metadata of the ComposablePart object.

Namespace:  System.ComponentModel.Composition.Primitives
Assembly:  System.ComponentModel.Composition (in System.ComponentModel.Composition.dll)

public virtual IDictionary<string, Object> Metadata { get; }

Property Value

Type: System.Collections.Generic.IDictionary<String, Object>
The metadata of the ComposablePart object. The default is an empty, read-only IDictionary<TKey, TValue> object.


The ComposablePart object has been disposed of.

If the ComposablePart object was created from a ComposablePartDefinition object, this property should return the result of Metadata.

Overrides of this property should return a read-only IDictionary<TKey, TValue> object with a case-sensitive, non-linguistic comparer, such as Ordinal, and should never return null. If the ComposablePart does not contain metadata, return an empty IDictionary<TKey, TValue> instead.
