Contains interfaces and classes that define various collections of objects, such as lists, queues, bit arrays, hash tables and dictionaries.
Classes
ArrayList |
Implements the IList interface using an array whose size is dynamically increased as required. |
BitArray |
Manages a compact array of bit values, which are represented as Booleans, where |
CaseInsensitiveComparer |
Compares two objects for equivalence, ignoring the case of strings. |
CaseInsensitiveHashCodeProvider |
Supplies a hash code for an object, using a hashing algorithm that ignores the case of strings. |
CollectionBase |
Provides the |
Comparer |
Compares two objects for equivalence, where string comparisons are case-sensitive. |
DictionaryBase |
Provides the |
Hashtable |
Represents a collection of key/value pairs that are organized based on the hash code of the key. |
Queue |
Represents a first-in, first-out collection of objects. |
ReadOnlyCollectionBase |
Provides the |
SortedList |
Represents a collection of key/value pairs that are sorted by the keys and are accessible by key and by index. |
Stack |
Represents a simple last-in-first-out (LIFO) non-generic collection of objects. |
StructuralComparisons |
Provides objects for performing a structural comparison of two collection objects. |
Structs
DictionaryEntry |
Defines a dictionary key/value pair that can be set or retrieved. |
Interfaces
ICollection |
Defines size, enumerators, and synchronization methods for all nongeneric collections. |
IComparer |
Exposes a method that compares two objects. |
IDictionary |
Represents a nongeneric collection of key/value pairs. |
IDictionaryEnumerator |
Enumerates the elements of a nongeneric dictionary. |
IEnumerable |
Exposes an enumerator, which supports a simple iteration over a non-generic collection. |
IEnumerator |
Supports a simple iteration over a non-generic collection. |
IEqualityComparer |
Defines methods to support the comparison of objects for equality. |
IHashCodeProvider |
Supplies a hash code for an object, using a custom hash function. |
IList |
Represents a non-generic collection of objects that can be individually accessed by index. |
IStructuralComparable |
Supports the structural comparison of collection objects. |
IStructuralEquatable |
Defines methods to support the comparison of objects for structural equality. |
