CompositionContainer::GetExportsCore Method

Returns a collection of all exports that match the conditions in the specified ImportDefinition object.

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

virtual IEnumerable<Export^>^ GetExportsCore(
	ImportDefinition^ definition, 
	AtomicComposition^ atomicComposition
) override


Type: System.ComponentModel.Composition.Primitives::ImportDefinition

The object that defines the conditions of the Export objects to get.

Type: System.ComponentModel.Composition.Hosting::AtomicComposition

The composition transaction to use, or nullptr to disable transactional composition.

Return Value

Type: System.Collections.Generic::IEnumerable<Export>
A collection of all the Export objects in this CompositionContainer object that match the conditions specified by definition.

Implementations should not treat cardinality-related mismatches as errors and should not throw exceptions for cardinality-related mismatches. For example, if the import requests exactly one export and the provider has either no matching exports or more than one, the GetExportsCore method should return an empty IEnumerable<T> collection of Export objects.
