RegisteredSubscriberCollection クラス
RegisteredSubscriber オブジェクトのコレクションを表します。
名前空間: Microsoft.SqlServer.Replication
アセンブリ: Microsoft.SqlServer.Rmo (Microsoft.SqlServer.Rmo.dll)
構文
'宣言
Public NotInheritable Class RegisteredSubscriberCollection _
Inherits ReplicationBaseCollection
'使用
Dim instance As RegisteredSubscriberCollection
public sealed class RegisteredSubscriberCollection : ReplicationBaseCollection
public ref class RegisteredSubscriberCollection sealed : public ReplicationBaseCollection
[<SealedAttribute>]

説明
コレクション内の RegisteredSubscriber オブジェクトには、[ Int32] インデックス値、またはサブスクライバ名である [ String] インデックス値を使用して、Item()()()() プロパティからアクセスできます。
この名前空間、クラス、またはメンバは、.NET Framework 2.0 でのみサポートされています。
スレッド セーフ
この型の public static (Microsoft Visual Basic では Shared) のすべてのメンバは、マルチスレッド操作で安全に使用できます。インスタンス メンバの場合は、スレッド セーフであるとは限りません。
使用例
この例では、RegisteredSubscribers プロパティからアクセスされる RegisteredSubscriberCollection の RegisteredSubscriber オブジェクトの数を確認します。
