ComposablePartExportProvider.GetExportsCore Method

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

Gets a collection of all exports in this provider 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

definition
Type: System.ComponentModel.Composition.Primitives.ImportDefinition
The ImportDefinition that defines the conditions of the Export to get.

atomicComposition
Type: System.ComponentModel.Composition.Hosting.AtomicComposition
The composition transaction to use, or nulla null reference (Nothing in Visual Basic) to disable transactional composition.

Return Value

Type: System.Collections.Generic.IEnumerable<Export>
A collection of all exports in this provider that match the specified conditions.

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