System.Collections Namespace

The System.Collections namespace contains interfaces and classes that define various collections of objects, such as lists, queues, bit arrays, hash tables and dictionaries.
Classes
Class Description
[Public class] ArrayList Implements the IList interface using an array whose size is dynamically increased as required.
[Public class] BitArray Manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on (1) and false indicates the bit is off (0).
[Public class] CaseInsensitiveComparer Compares two objects for equivalence, ignoring the case of strings.
[Public class] CaseInsensitiveHashCodeProvider Obsolete. Supplies a hash code for an object, using a hashing algorithm that ignores the case of strings.
[Public class] CollectionBase Provides the abstract base class for a strongly typed collection.
[Public class] Comparer Compares two objects for equivalence, where string comparisons are case-sensitive.
[Public class] DictionaryBase Provides the abstract base class for a strongly typed collection of key/value pairs.
[Public class] Hashtable Represents a collection of key/value pairs that are organized based on the hash code of the key.
[Public class] Queue Represents a first-in, first-out collection of objects.
[Public class] ReadOnlyCollectionBase Provides the abstract base class for a strongly typed non-generic read-only collection.
[Public class] SortedList Represents a collection of key/value pairs that are sorted by the keys and are accessible by key and by index.
[Public class] Stack Represents a simple last-in-first-out (LIFO) non-generic collection of objects.
Structures
Structure Description
[Public structure] DictionaryEntry Defines a dictionary key/value pair that can be set or retrieved.
Interfaces
Interface Description
[Public interface] ICollection Defines size, enumerators, and synchronization methods for all nongeneric collections.
[Public interface] IComparer Exposes a method that compares two objects.
[Public interface] IDictionary Represents a nongeneric collection of key/value pairs.
[Public interface] IDictionaryEnumerator Enumerates the elements of a nongeneric dictionary.
[Public interface] IEnumerable Exposes the enumerator, which supports a simple iteration over a non-generic collection.
[Public interface] IEnumerator Supports a simple iteration over a nongeneric collection.
[Public interface] IEqualityComparer Defines methods to support the comparison of objects for equality.
[Public interface] IHashCodeProvider Obsolete. Supplies a hash code for an object, using a custom hash function.
[Public interface] IList Represents a non-generic collection of objects that can be individually accessed by
