The FCL provides a set of general-purpose data structures such as System.Array , ArrayList , Hashtable , Queue , Stack , BitArray , and more. Standardized design patterns using common base types and public interfaces allow consistent handling of collections throughout the FCL for both predefined and user -defined collection types (see Chapter 7). For more information, see the following namespaces: System.Collections System.Collections.Specialized An important related type in another namespace is System.Array . |
