Classes

Algorithms

Algorithms contains a number of static methods that implement algorithms that work on collections. Most of the methods deal with the standard generic collection interfaces such as IEnumerable<T>, ICollection<T> and IList<T>.

Bag<T>

Bag<T> is a collection that contains items of type T. Unlike a Set, duplicate items (items that compare equal to each other) are allowed in an Bag.

CollectionBase<T>

CollectionBase is a base class that can be used to more easily implement the generic ICollection<T> and non-generic ICollection interfaces.

ListBase<T>

ListBase is an abstract class that can be used as a base class for a read-write collection that needs to implement the generic IList<T> and non-generic IList collections. The derived class needs to override the following methods: Count, Clear, Insert, RemoveAt, and the indexer. The implementation of all the other methods in IList<T> and IList are handled by ListBase.

MultiDictionaryBase<TKey, TValue>

MultiDictionaryBase is a base class that can be used to more easily implement a class that associates multiple values to a single key. The class implements the generic IDictionary<TKey, ICollection<TValue>> interface.

OrderedMultiDictionary<TKey, TValue>

The OrderedMultiDictionary class that associates values with a key. Unlike an OrderedDictionary, each key can have multiple values associated with it. When indexing an OrderedMultidictionary, instead of a single value associated with a key, you retrieve an enumeration of values.

All of the key are stored in sorted order. Also, the values associated with a given key are kept in sorted order as well.

When constructed, you can chose to allow the same value to be associated with a key multiple times, or only one time.

OrderedMultiDictionary<TKey, TValue>.View

The OrderedMultiDictionary<TKey,TValue>.View class is used to look at a subset of the keys and values inside an ordered multi-dictionary. It is returned from the Range, RangeTo, RangeFrom, and Reversed methods.

ReadOnlyCollectionBase<T>

ReadOnlyCollectionBase is a base class that can be used to more easily implement the generic ICollection<T> and non-generic ICollection interfaces for a read-only collection: a collection that does not allow adding or removing elements.

Set<T>

Set<T> is a collection that contains items of type T. The item are maintained in a haphazard, unpredictable order, and duplicate items are not allowed.

Structs

Pair<TFirst, TSecond>

Stores a pair of objects within a single struct. This struct is useful to use as the T of a collection, or as the TKey or TValue of a dictionary.

Delegates

BinaryPredicate<T>

The BinaryPredicate delegate type encapsulates a method that takes two items of the same type, and returns a boolean value representating some relationship between them. For example, checking whether two items are equal or equivalent is one kind of binary predicate.
