名稱	Description
ImportDefinition()	初始化 ImportDefinition 類別的新執行個體。
ImportDefinition(Expression<Func<ExportDefinition,Boolean>>, String, ImportCardinality, Boolean, Boolean)	初始化一個新的類別實例 ImportDefinition ，包含指定的約束、合約名稱和基數，並指示匯入定義是否可重組或為前置條件。
ImportDefinition(Expression<Func<ExportDefinition,Boolean>>, String, ImportCardinality, Boolean, Boolean, IDictionary<String,Object>)	初始化一個新實例 ImportDefinition ，包含指定的限制、合約名稱、基數及元資料，並指示匯入定義是否可重組或為前置條件。

備註

呼叫此建構子的導出型別必須覆蓋該 Constraint 屬性，並可選擇覆蓋 Cardinality、和 IsPrerequisite IsRecomposable 屬性。

Public Sub New (constraint As Expression(Of Func(Of ExportDefinition, Boolean)), contractName As String, cardinality As ImportCardinality, isRecomposable As Boolean, isPrerequisite As Boolean)

參數

constraint: Expression<Func<ExportDefinition,Boolean>>

包含 Func<T,TResult> 定義條件的 Export 物件的表達式，必須符合為滿足匯入定義而符合條件。

contractName: String

合約名稱。

cardinality: ImportCardinality

其中一個枚舉值，表示匯入定義所需物件的 Export 基數。

isRecomposable: Boolean

true 指定匯入定義可在物件生命 ComposablePart 週期內多次滿足;否則， false。

isPrerequisite: Boolean

true指定必須滿足進口定義才能ComposablePart開始產生出口物件;否則，。 false

例外狀況

ArgumentNullException

constraint 為 null。

ArgumentException

cardinality 不是的 ImportCardinality值之一。
