Namespace: System.Collections.Specialized

The System.Collections.Specialized namespace contains specialized and strongly-typed collections; for example, a linked list dictionary, a bit vector, and collections that contain only strings.

Members of System.Collections.Specialized Namespace

Class	Description
class CollectionsUtil	Creates collections that ignore the case in strings.
class HybridDictionary	Implements by using a ListDictionary while the collection is small, and then switching to a Hashtable when the collection gets large.
class NameObjectCollectionBase.KeysCollection	Represents a collection of the String keys of a collection.
class ListDictionary	Implements using a singly linked list. Recommended for collections that typically contain 10 items or less.
class NameObjectCollectionBase	Provides the base class for a sorted collection of associated String keys and Object values that can be accessed either with the key or with the index.
class NameValueCollection	Represents a sorted collection of associated String keys and String values that can be accessed either with the key or with the index.
class StringCollection	Represents a collection of strings.
class StringDictionary	Implements a hashtable with the key strongly typed to be a string rather than an object.
class StringEnumerator	Supports a simple iteration over a StringCollection.

Structure	Description
structure BitVector32	Provides a simple structure that stores Boolean values and small integers in 32 bits of memory.
structure BitVector32.Section	Represents an section of the vector that can contain a integer number.
