HttpModuleCollection.GetKey Method
.NET Framework 2.0
Returns the key (name) of the IHttpModule object at the specified numerical index.
Namespace: System.Web
Assembly: System.Web (in system.web.dll)
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.
