ItemCollection ItemCollection ItemCollection ItemCollection Class

Definition

Important

This API is not CLS-compliant.

A base class for ObjectItemCollection, EdmItemCollection, and StorageMappingItemCollection classes. An ItemCollection class is an abstract class and provides the core API for loading and holding the in-memory metadata. This class is derived from the ReadOnlyMetadataCollection<T> class.
