StateManagedCollection::GetKnownTypes Method ()

 

When overridden in a derived class, gets an array of IStateManager types that the StateManagedCollection collection can contain.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

protected:
virtual array<Type^>^ GetKnownTypes()

Return Value

Type: array<System::Type^>^

An ordered array of Type objects that identify the types of IStateManager objects the collection can contain. The default implementation returns null.

The GetKnownTypes method is called internally by the StateManagedCollection collection in its implementation of the IStateManager::SaveViewState method. Derived collections override the GetKnownTypes method to return an array of Type objects that represent the types the collection can contain.

The following code example demonstrates how a strongly typed StateManagedCollection class implements the GetKnownTypes method. The CycleCollection implementation of GetKnownTypes returns a Type array of known types, including Bicycle and Tricycle types. This code example is part of a larger example provided for the StateManagedCollection class.
