HttpModuleCollection クラス

IHttpModule オブジェクトのコレクションに対して、インデックス付けおよび取得を実行できるようにする手段を提供します。

名前空間: System.Web
アセンブリ: System.Web (system.web.dll 内)
構文

Visual Basic (宣言)

Public NotInheritable Class
 HttpModuleCollection
    Inherits NameObjectCollectionBase

Visual Basic (使用法)

Dim instance As HttpModuleCollection

public sealed class HttpModuleCollection :
 NameObjectCollectionBase

C++

public ref class HttpModuleCollection sealed
 : public NameObjectCollectionBase

public final class HttpModuleCollection extends
 NameObjectCollectionBase

JScript

public final class HttpModuleCollection extends
 NameObjectCollectionBase

使用例

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。
