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.
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.
Provides a simple structure that stores Boolean values and small integers in 32 bits of memory.
Represents a section of the vector that can contain an integer number.
Notifies listeners of dynamic changes, such as when an item is added and removed or the whole list is cleared.
Represents an indexed collection of key/value pairs.
Describes the action that caused a CollectionChanged event.
Represents the method that handles the CollectionChanged event.
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.
