Gets a collection of all exports in this provider that match the conditions of the specified import.

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 ImportDefinition that defines the conditions of the Export to get.

atomicComposition: AtomicComposition

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

Returns

IEnumerable<Export>

A collection of all exports in this provider that match the specified conditions.

Remarks

Implementers 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 no matching exports or more than one, the GetExportsCore method should return an empty IEnumerable<T> collection of Export objects.
