SynchronizationOption 列挙体

コンポーネントに必要な自動同期の種類を指定します。

名前空間: System.EnterpriseServices
アセンブリ: System.EnterpriseServices (system.enterpriseservices.dll 内)
構文

Visual Basic (宣言)

<SerializableAttribute> _
Public Enumeration SynchronizationOption

Visual Basic (使用法)

Dim instance As SynchronizationOption

C#

[SerializableAttribute] 
public enum SynchronizationOption

C++

[SerializableAttribute] 
public enum class SynchronizationOption

J#

/** @attribute SerializableAttribute() */ 
public enum SynchronizationOption

JScript

SerializableAttribute 
public enum SynchronizationOption

メンバ

	メンバ名	説明
	Disabled	COM+ は、オブジェクトのコンテキストを確認する場合に、コンポーネントの同期要件を無視します。
	NotSupported	この値が指定されたオブジェクトは、その呼び出し元のステータスにかかわらず、同期には関与しません。この設定は、非トランザクションでありジャスト イン タイム (JIT: Just-In-Time) アクティベーションを使用しないコンポーネントに限り使用できます。
	Required	コンポーネントから作成されたすべてのオブジェクトの同期をとります。
	RequiresNew	この値が指定されたオブジェクトは、呼び出しに関係するすべてのコンポーネントに代わって COM+ がコンテキストとアパートメントを管理する新しい同期に関与する必要があります。
	Supported	この値が指定されたオブジェクトが存在する場合、このオブジェクトは同期に関与します。
