アセンブリ: System.Web (system.web.dll 内)
構文解説運用および操作の担当者は、ASP.NET Health Monitoring を使用して、配置されている Web アプリケーションを管理できます。System.Web.Management 名前空間には、アプリケーションの状態データをパッケージ化する状態イベント型、およびそのデータを処理するプロバイダ型が含まれます。また、状態イベント管理を支援するサポート型も含まれます。
WebBaseEventCollection クラスは、SqlWebEventProvider などのプロバイダに状態監視イベントのコレクションを配信するために使用します。
使用例WebBaseEventCollection クラスを使用するコード例を次に示します。
