ExportProvider.TryGetExports 方法

定義

取得所有符合指定進口條件的出口。

public:
 bool TryGetExports(System::ComponentModel::Composition::Primitives::ImportDefinition ^ definition, System::ComponentModel::Composition::Hosting::AtomicComposition ^ atomicComposition, [Runtime::InteropServices::Out] System::Collections::Generic::IEnumerable<System::ComponentModel::Composition::Primitives::Export ^> ^ % exports);
public bool TryGetExports(System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition? atomicComposition, out System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export>? exports);
public bool TryGetExports(System.ComponentModel.Composition.Primitives.ImportDefinition definition, System.ComponentModel.Composition.Hosting.AtomicComposition atomicComposition, out System.Collections.Generic.IEnumerable<System.ComponentModel.Composition.Primitives.Export> exports);
member this.TryGetExports : System.ComponentModel.Composition.Primitives.ImportDefinition * System.ComponentModel.Composition.Hosting.AtomicComposition * seq -> bool
Public Function TryGetExports (definition As ImportDefinition, atomicComposition As AtomicComposition, ByRef exports As IEnumerable(Of Export)) As Boolean

參數

definition
ImportDefinition

定義要取得的 Export 物件條件的物件。

atomicComposition
AtomicComposition

這是創作的交易容器。

exports
IEnumerable<Export>

當此方法回傳時,包含一組 Export 符合條件 ImportDefinition的物件集合(若找到),則為空 IEnumerable<T> 物件。 這個參數會未初始化傳遞。

傳回

true若 是 或 且 且 零個Cardinality物件符合指定ZeroOrOne條件;ZeroOrMoreExport 或 且 ImportDefinitiontrue 恰好有一個Cardinality物件符合指定ZeroOrOne條件;否則 。 ExactlyOneExportImportDefinitionfalse

例外狀況

definitionnull
