HttpModuleCollection 類別
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
提供方法來編製索引並擷取 IHttpModule 物件集合。

範例
下列程式碼範例示範 AllKeys 類別的 HttpModuleCollection 屬性和 GetKey 和 CopyTo 方法。 此範例會從目前 HttpContext 物件取得目前要求的應用程式物件。 然後，它會從應用程式實例擷取 HttpModuleCollection 物件，並顯示物件的名稱 IHttpModule 。

屬性
| AllKeys |
取得字串陣列，包含在 HttpModuleCollection 中所有索引鍵 (模組名稱)。 |
| Count |
取得 NameObjectCollectionBase 執行個體中包含的索引鍵/值組數目。 (繼承來源 NameObjectCollectionBase) |
| IsReadOnly |
取得或設定值，表示 NameObjectCollectionBase 執行個體是否為唯讀。 (繼承來源 NameObjectCollectionBase) |
| Item[Int32] |
以指定的數值索引從 IHttpModule 取得 HttpModuleCollection 物件。 |
| Item[String] |
以指定名稱從 IHttpModule 取得 HttpModuleCollection 物件。 |
| Keys |
取得 NameObjectCollectionBase.KeysCollection 執行個體，其中包含 NameObjectCollectionBase 執行個體內的所有索引鍵。 (繼承來源 NameObjectCollectionBase) |
方法
明確介面實作
| ICollection.CopyTo(Array, Int32) |
從目標陣列的指定索引開始，將整個 NameObjectCollectionBase 複製到相容的一維 Array。 (繼承來源 NameObjectCollectionBase) |
| ICollection.IsSynchronized |
取得值，表示是否要同步處理 (執行緒安全) 對 NameObjectCollectionBase 物件的存取。 (繼承來源 NameObjectCollectionBase) |
| ICollection.SyncRoot |
取得可用來同步處理對 NameObjectCollectionBase 物件之存取的物件。 (繼承來源 NameObjectCollectionBase) |
擴充方法
| Cast<TResult>(IEnumerable) |
將 IEnumerable 的項目轉換成指定的型別。 |
| OfType<TResult>(IEnumerable) |
根據指定的型別來篩選 IEnumerable 的項目。 |
| AsParallel(IEnumerable) |
啟用查詢的平行化作業。 |
| AsQueryable(IEnumerable) |
