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)

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 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.
