DeviceSpecificChoiceCollection Class
Assembly: System.Web.Mobile (in system.web.mobile.dll)
Accessing the Choices property of a DeviceSpecific object retrieves a DeviceSpecificChoiceCollection object. This collection implements the ICollection interface (through the ArrayListCollectionBase object); it implements all properties and methods of the ICollection interface.
The following code example shows how to use the DeviceSpecificChoiceCollection class to gain access to the choices in a DeviceSpecific/Choice construct. For your convenience, a Web.config file containing the filters follows the example code.
