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
| 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. |
