HttpModuleCollection Class
Provides a way to index and retrieve a collection of IHttpModule objects.
Assembly: System.Web (in System.Web.dll)
The following code example demonstrates the AllKeys property and the GetKey and CopyTo methods of the HttpModuleCollection class. The example gets the application object for the current request from the current HttpContext object. It then extracts the HttpModuleCollection object from the application instance and displays the names of the IHttpModule objects.

Dim i As Integer Dim myHttpContext As HttpContext = HttpContext.Current ' Get the application 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 httpModuleName As string = myHttpModuleCollection.GetKey(1) Response.Write("The name of the HttpModule object at index 1" + " is " +"'"+ httpModuleName+"'." + "<br><br>") Dim allModules() As string = myHttpModuleCollection.AllKeys ' Display the names of all HttpModule objects.
