System.Collections.Specialized Namespace ()

.NET Framework Class Library

System.Collections.Specialized Namespace

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.

Classes

	Class	Description
	CollectionChangedEventManager	Provides a WeakEventManager implementation so that you can use the "weak event listener" pattern to attach listeners for the CollectionChanged event.
	CollectionsUtil	Creates collections that ignore the case in strings.
	HybridDictionary	Implements IDictionary by using a ListDictionary while the collection is small, and then switching to a Hashtable when the collection gets large.
	ListDictionary	Implements IDictionary using a singly linked list. Recommended for collections that typically contain 10 items or less.
	NameObjectCollectionBase	Provides the abstract base class for a collection of associated String keys and Object values that can be accessed either with the key or with the index.
	NameObjectCollectionBase..::.KeysCollection	Represents a collection of the String keys of a collection.
	NameValueCollection	Represents a collection of associated String keys and String values that can be accessed either with the key or with the index.
	NotifyCollectionChangedEventArgs	Provides data for the CollectionChanged event.
	OrderedDictionary	Represents a collection of key/value pairs that are accessible by the key or index.
	StringCollection	Represents a collection of strings.
	StringDictionary	Implements a hash table with the key and the value strongly typed to be strings rather than objects.
	StringEnumerator	Supports a simple iteration over a StringCollection.

Structures

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

Interfaces

	Interface	Description
	INotifyCollectionChanged	Notifies listeners of dynamic changes, such as when items get added and removed or the whole list is refreshed.
	IOrderedDictionary	Represents an indexed collection of key/value pairs.

Delegates

	Delegate	Description
	NotifyCollectionChangedEventHandler	Represents the method that handles the CollectionChanged event.

Enumerations

	Enumeration	Description
	NotifyCollectionChangedAction	Describes the action that caused a CollectionChanged event.
