Disabled 0

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。COM+ ignores the synchronization requirements of the component when determining context for the object.

NotSupported 1

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。An object with this value never participates in synchronization, regardless of the status of its caller. 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のみ使用できます。This setting is only available for components that are non-transactional and do not use just-in-time (JIT) activation.

Required 3

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。Ensures that all objects created from the component are synchronized.

RequiresNew 4

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。An object with this value must participate in a new synchronization where COM+ manages contexts and apartments on behalf of all components involved in the call.

Supported 2

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。An object with this value participates in synchronization, if it exists.

SynchronizationOption型の使用方法を次のコード例に示します。The following code example demonstrates the use of the SynchronizationOption type.

#using <System.EnterpriseServices.dll>

using namespace System;
using namespace System::EnterpriseServices;

// References:
// System.EnterpriseServices

// An instance of this class will not join an activity, but can share its
// caller's context even if its caller is configured as NotSupported,
// Supported, Required, or RequiresNew.
[Synchronization(SynchronizationOption::Disabled)]
public ref class SynchronizationAttribute_SynchronizationDisabled :
    public ServicedComponent
{
};

// An instance of this class will not join an activity, and will share its
// caller's context only if its caller is also configured as NotSupported.
[Synchronization(SynchronizationOption::NotSupported)]
public ref class SynchronizationAttribute_SynchronizationNotSupported :
    public ServicedComponent
{
};

// An instance of this class will join its caller's activity if one exists.
[Synchronization(SynchronizationOption::Supported)]
public ref class SynchronizationAttribute_SynchronizationSupported :
    public ServicedComponent
{
};

// An instance of this class will join its caller's activity if one exists.
// If not, a new activity will be created for it.
[Synchronization(SynchronizationOption::Required)]
public ref class SynchronizationAttribute_SynchronizationRequired :
    public ServicedComponent
{
};

// A new activity will always be created for an instance of this class.
[Synchronization(SynchronizationOption::RequiresNew)]
public ref class SynchronizationAttribute_SynchronizationRequiresNew :
    public ServicedComponent
{
};

using System.EnterpriseServices;

// caller's context even if its caller is configured as NotSupported,

[Synchronization(SynchronizationOption.Disabled)]
public class SynchronizationAttribute_SynchronizationDisabled :
    ServicedComponent
{
}

// An instance of this class will not join an activity, and will share its
// caller's context only if its caller is also configured as NotSupported.
[Synchronization(SynchronizationOption.NotSupported)]
public class SynchronizationAttribute_SynchronizationNotSupported :
    ServicedComponent
{
}

// An instance of this class will join its caller's activity if one exists.
[Synchronization(SynchronizationOption.Supported)]
public class SynchronizationAttribute_SynchronizationSupported :
    ServicedComponent
{
}

// An instance of this class will join its caller's activity if one exists.
// If not, a new activity will be created for it.
[Synchronization(SynchronizationOption.Required)]
public class SynchronizationAttribute_SynchronizationRequired :
    ServicedComponent
{
}

// A new activity will always be created for an instance of this class.
[Synchronization(SynchronizationOption.RequiresNew)]
