Thenamespace contains specialized and strongly-typed collections; for example, a linked list dictionary, a bit vector, and collections that contain only strings.
Creates collections that ignore the case in strings.
Represents a collection of the String keys of a collection.
Implements IDictionary using a singly linked list. Recommended for collections that typically include fewer than 10 items.
Provides data for the CollectionChanged event.
Represents a collection of key/value pairs that are accessible by the key or index.
Represents a collection of strings.
Implements a hash table with the key and the value strongly typed to be strings rather than objects.
Supports a simple iteration over a StringCollection.
Specialized collections are collections with highly specific purposes. NameValueCollection is based on NameObjectCollectionBase; however, NameValueCollection accepts multiple values per key, whereas NameObjectCollectionBase accepts only one value per key.
The CollectionsUtil class creates instances of case-insensitive collections.
Some collections transform. For example, the HybridDictionary class starts as a ListDictionary and becomes a Hashtable when it becomes large. The KeyedCollection<TKey, TItem> is a list but it also creates a lookup dictionary when the number of elements reaches a specified threshold.
