The Specialized Collections
The NET Framework provides some specialized collections that are optimized to work on a specific type of data or in a specific way These non-generic collection classes are defined inside the SystemCollectionsSpecialized namespace They are synopsized in the following table:
Specialized Collection CollectionsUtil HybridDictionary Description Contains factory methods that create collections that store strings, but ignore case differences A collection that uses a ListDictionary to store key/value pairs when there are few elements in the collection When the collection grows beyond a certain size, a Hashtable is automatically used to store the elements A collection that stores key/value pairs in a linked list It is recommended only for small collections A sorted collection of key/value pairs in which both the key and value are of type string A collection of key/value pairs that can be indexed A collection optimized for storing strings A hash table of key/value pairs in which both the key and the value are of type string
PART II
ListDictionary NameValueCollection OrderedDictionary StringCollection StringDictionary
SystemCollections also defines three abstract base classes, CollectionBase, ReadOnlyCollectionBase, and DictionaryBase, which can be inherited and used as a starting point for developing custom specialized collections
The Generic Collections
The addition of generics greatly expanded the Collections API, essentially doubling the amount of collection classes and interfaces The generic collections are declared in the SystemCollectionsGeneric namespace In many cases, the generic collection classes are simply generic equivalents of the non-generic classes discussed earlier However, the correspondence is not one-to-one For example, there is a generic collection called LinkedList that implements a doubly linked list, but no non-generic equivalent In some cases, parallel functionality exists between the generic and non-generic classes, but the names differ For example, the generic version of ArrayList is called List, and the generic
Part II:
Exploring the C# Library
version of Hashtable is called Dictionary Also, the specific contents of the various interfaces and classes contain minor reorganizations, with some functionality shifting from one interface to another, for example However, overall, if you understand the non-generic collections, then you can easily use the generic collections In general, the generic collections work in the same way as the non-generic collections with the exception that a generic collection is type-safe Thus, a generic collection can store only items that are compatible with its type argument Therefore, if you want a collection that is capable of storing unrelated, mixed types, you should use one of the non-generic classes However, for all cases in which a collection is storing only one type of object, then a generic collection is your best choice The generic collections are defined by a set of interfaces and the classes that implement those interfaces Each is described by the following sections
The Generic Interfaces
SystemCollectionsGeneric defines a number of generic interfaces, all of which parallel their corresponding non-generic counterparts The generic interfaces are summarized in Table 25-10
The ICollection<T> Interface
The ICollection<T> interface defines those features that all generic collections have in common It inherits the IEnumerable and IEnumerable<T> interfaces ICollection<T> is the generic version of the non-generic ICollection interface However, there are some differences between the two ICollection<T> defines the following properties: int Count { get; } bool IsReadOnly { get; } Count contains the number of items currently held in the collection IsReadOnly is true if the collection is read-only It is false if the collection is read/write
Interface ICollection<T> IComparer<T> IDictionary<TKey, TValue> IEnumerable<T> IEnumerator<T> IEqualityComparer<T> IList<T> ISet<T>
TABLE 25-10
Description Defines the foundational features for the generic collections Defines the generic Compare( ) method that performs a comparison on objects stored in a collection Defines a generic collection that consists of key/value pairs Defines the generic GetEnumerator( ) method, which supplies the enumerator for a collection class Provides members that enable the contents of a collection to be obtained one at a time Compares two objects for equality Defines a generic collection that can be accessed via an indexer Defines a generic collection that represents a set
