AggregateExportProvider.GetExportsCore Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets all the exports that match the conditions of the specified import.

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

Syntax

'Declaration
Protected Overrides Function GetExportsCore ( _
    definition As ImportDefinition, _
    atomicComposition As AtomicComposition _
) As IEnumerable(Of Export)
protected override IEnumerable<Export> GetExportsCore(
    ImportDefinition definition,
    AtomicComposition atomicComposition
)

Parameters

Return Value

Type: System.Collections.Generic.IEnumerable<Export>
A collection that contains all the exports that match the specified condition.

Remarks

Implementers should not treat cardinality-related mismatches as errors and are not expected to throw exceptions in those cases.

For example, if the import requests exactly one export and the provider has either no matching exports or more than one, the method should return an empty IEnumerable<T> collection of Export.
