ExportProvider.TryGetExports 方法

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

参数

返回

true如果Cardinality为ZeroOrOne或ZeroOrMore并且存在与指定Export条件匹配的零ImportDefinition对象;true如果Cardinality为ZeroOrOne或ExactlyOne与指定Export条件完全匹配，则为零ImportDefinition;否则为 false。

例外
