サンプル 2: クレーム プロバイダーを記述する
最終更新日: 2010年8月3日
適用対象: SharePoint Foundation 2010
クレーム プロバイダーを記述する
次の例は、クレーム プロバイダーを記述する方法を示しています。この例の実装では、エンティティ、解決、および検索がサポートされますが、階層はサポートされません。階層をサポートする方法を示すコード例については、SPClaimProvider クラスの FillHierarchy() メソッドの参照トピックを参照してください。
クレーム プロバイダーを記述するには、まず、SPClaimProvider クラスから派生するクラスを作成します。このトピックは、読者が既に「[方法] クレーム プロバイダーを作成する」トピックを読んでいることを前提としています。
クレーム プロバイダーの作成の詳細とチュートリアルについては、「クレームに関するチュートリアル: SharePoint 2010 のクレーム プロバイダーを記述する」を参照してください。

追加のコード例、および SPClaimProvider クラスとそのメンバーの詳細については、「SPClaimProvider」を参照してください。また、「SharePoint SPIdentity Team Blog」および「Share-n-dipity (英語)」を定期的に確認し、追加の例と更新がないかどうかを確かめてください。 |
