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

protected:
 override System::Collections::Generic::IEnumerable<System::ComponentModel::Composition::Primitives::Export ^> ^ GetExportsCore(System::ComponentModel::Composition::Primitives::ImportDefinition ^ definition, System::ComponentModel::Composition::Hosting::AtomicComposition ^ atomicComposition);

protected override System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export>? GetExportsCore (System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition? atomicComposition);

protected override System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export> GetExportsCore (System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition atomicComposition);

override this.GetExportsCore : System.ComponentModel.Composition.Primitives.ImportDefinition * System.ComponentModel.Composition.Hosting.AtomicComposition -> seq<System.ComponentModel.Composition.Primitives.Export>

Protected Overrides Function GetExportsCore (definition As ImportDefinition, atomicComposition As AtomicComposition) As IEnumerable(Of Export)

Parameters

definition: ImportDefinition

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

atomicComposition: AtomicComposition

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

Returns

IEnumerable<Export>

A collection of all the Export objects in this CompositionContainer object that match the conditions specified by definition.

Remarks

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.
