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。
<%@ Page language="VB" %>
<%@ Import Namespace = "System.Data" %>
<script runat="server">
' System.Web.HttpModuleCollection.AllKeys;GetKey;CopyTo
Sub Page_Load(Sender As Object, e As EventArgs )
' Get the HttpContext object for the current request.

Dim myHttpApplication As HttpApplication = myHttpContext.ApplicationInstance
' Get the collection of all HTTPModule objects for the current application.
Dim myHttpModuleCollection As HttpModuleCollection = myHttpApplication.Modules
' Get the name of the HttpModule object at index 1.

Dim allModules() As string = myHttpModuleCollection.AllKeys
' Display the names of all HttpModule objects.

myHttpModuleCollection.CopyTo(httpModuleArray,0)
Response.Write("<br><br><b>Successfully copied the HttpModule objects in the HttpModuleCollection to an array."+ "<br>Displaying the HttpModule objects in the array:</b><br>")
For i=0 To httpModuleArray.Length -1
Response.Write("Module" + i.ToString() + ": " + httpModuleArray.GetValue(i).ToString() + "<br>")
