メンバ

メンバ名	説明
Anonymous	プル サブスクリプションは、MakePullSubscriptionWellKnown を使用して、パブリッシャで明示的に登録されません。パブリッシャ側でサブスクリプションを登録せずにサブスクリプションを作成する場合、匿名サブスクリプションは必須です。これは、Web 同期などの、サブスクリプションの構成時にパブリッシャに SQL Server 接続を確立できない場合に必要です。
Global	サブスクリプションはサーバー サブスクリプションです。通常、この種類のサブスクリプションは、他のサブスクライバにデータを再パブリッシュするサブスクライバで使用されます。
Local	サブスクリプションはクライアント サブスクリプションです。この種類のサブスクリプションは、ほとんどのサブスクライバに適しています。

解説

この名前空間、クラス、またはメンバは、Microsoft .NET Framework のバージョン 2.0 でのみサポートされています。
