Gets a list of export definitions that match the constraint defined by the specified ImportDefinition object.

public:
 virtual System::Collections::Generic::IEnumerable<Tuple<System::ComponentModel::Composition::Primitives::ComposablePartDefinition ^, System::ComponentModel::Composition::Primitives::ExportDefinition ^> ^> ^ GetExports(System::ComponentModel::Composition::Primitives::ImportDefinition ^ definition);

public virtual System.Collections.Generic.IEnumerable<Tuple<System.ComponentModel.Composition.Primitives.ComposablePartDefinition,System.ComponentModel.Composition.Primitives.ExportDefinition>> GetExports (System.ComponentModel.Composition.Primitives.ImportDefinition definition);

abstract member GetExports : System.ComponentModel.Composition.Primitives.ImportDefinition -> seq<System.ComponentModel.Composition.Primitives.ComposablePartDefinition * System.ComponentModel.Composition.Primitives.ExportDefinition>
override this.GetExports : System.ComponentModel.Composition.Primitives.ImportDefinition -> seq<System.ComponentModel.Composition.Primitives.ComposablePartDefinition * System.ComponentModel.Composition.Primitives.ExportDefinition>

Public Overridable Function GetExports (definition As ImportDefinition) As IEnumerable(Of Tuple(Of ComposablePartDefinition, ExportDefinition))

Parameters

definition: ImportDefinition

The conditions of the ExportDefinition objects to be returned.

Returns

IEnumerable<Tuple<ComposablePartDefinition,ExportDefinition>>

A collection of Tuple<T1,T2> containing the ExportDefinition objects and their associated ComposablePartDefinition objects for objects that match the constraint specified by definition.

Exceptions

ObjectDisposedException

The ComposablePartCatalog object has been disposed of.

ArgumentNullException

definition is null.

Remarks

Overrides of this method should never return null. If no ExportDefinition matches the conditions defined by definition, return an empty IEnumerable<T> object.
