Syntax

'Declaration

Parameters

Return Value

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

Remarks

Overrides of this method should not treat cardinality-related mismatches as errors, and should not throw exceptions in those cases. For example, if Cardinality is ExactlyOne and there are zero Export objects that match the conditions of the specified ImportDefinition, an empty IEnumerable<T> collection should be returned.
