HttpModuleCollection.CopyTo(Array, Int32) 方法

定義

命名空間:
System.Web
組件:
System.Web.dll

將模組集合的成員從陣列指定的索引開始複製到 Array。

public:
 void CopyTo(Array ^ dest, int index);
public void CopyTo(Array dest, int index);
member this.CopyTo : Array * int -> unit
Public Sub CopyTo (dest As Array, index As Integer)

參數

dest
Array

目的地 Array。

index
Int32

複製開始的目的地 Array 索引。

範例

以下程式碼範例展示了AllKeys該HttpModuleCollection類別的性質以及 GetKey 和 CopyTo 方法。 範例中從當前 HttpContext 物件取得當前請求的應用程式物件。 接著它會從應用程式實例中擷取物件 HttpModuleCollection ，並顯示物件 IHttpModule 名稱。
