If you need to cast a generic type parameter to a specific type, we can cast it to a object and do the casting like below: } type storedclass { get;

} is there a better way to achieve this, rather than casting it to an object and then to a specific type? While it seems normal to be able to write code like this: Cases are added to the list by a registration process: } now you can freely use: Now i wish to cast it to a generic observable collections: Datatable, idatatable { protected datatable.</p> /// list of test cases to execute std::vector< itest* > list_; I understand i can iterate over the list and add each individual item to the observable collection.
