System.Collections.Generic Namespace

The System.Collections.Generic namespace contains interfaces and classes that define generic collections, which allow users to create strongly typed collections that provide better type safety and performance than non-generic strongly typed collections.

Classes

	Class	Description
	ComparerT	Provides a base class for implementations of the IComparerT generic interface.
	DictionaryTKey, TValue	Represents a collection of keys and values.
	DictionaryTKey, TValueKeyCollection	Represents the collection of keys in a DictionaryTKey, TValue. This class cannot be inherited.
	DictionaryTKey, TValueValueCollection	Represents the collection of values in a DictionaryTKey, TValue. This class cannot be inherited.
	EqualityComparerT	Provides a base class for implementations of the IEqualityComparerT generic interface.
	HashSet2T
	ListT	Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists.
	StackT	Represents a variable size last-in-first-out (LIFO) collection of instances of the same arbitrary type.

Structures

	Structure	Description
	DictionaryTKey, TValueEnumerator	Enumerates the elements of a DictionaryTKey, TValue.
	DictionaryTKey, TValueKeyCollectionEnumerator	Enumerates the elements of a DictionaryTKey, TValueKeyCollection.
	DictionaryTKey, TValueValueCollectionEnumerator	Enumerates the elements of a DictionaryTKey, TValueValueCollection.
	KeyValuePairTKey, TValue	Defines a key/value pair that can be set or retrieved.
	ListTEnumerator	Enumerates the elements of a ListT.
	StackTEnumerator	Enumerates the elements of a StackT.

Interfaces

	Interface	Description
	ICollectionT	Defines methods to manipulate generic collections.
	IEnumerableT	Exposes the enumerator, which supports a simple iteration over a collection of a specified type.
	IEnumeratorT	Supports a simple iteration over a generic collection.
	IListT	Represents a collection of objects that can be individually accessed by index.
