HttpModuleCollection.CopyTo メソッド
アセンブリ: System.Web (system.web.dll 内)

Dim instance As HttpModuleCollection Dim dest As Array Dim index As Integer instance.CopyTo(dest, index)

HttpModuleCollection クラスの AllKeys プロパティおよび GetKey メソッドと CopyTo メソッドを次のコード例に示します。この例では、現在の要求のアプリケーション オブジェクトを現在の HttpContext オブジェクトから取得します。次に、HttpModuleCollection オブジェクトをアプリケーション インスタンスから抽出し、IHttpModule オブジェクトの名前を表示します。
