1. Understanding C # Collections

System.Collections namespaces System.CollectionsNamespaces contain interfaces and classes that define a collection of various objects such as lists, queues, bit arrays, hash tables, and dictionaries.class

	class	description
	ArrayList	The IList interface is implemented using an array of size that dynamically increases on demand.
	BitArray	Manages a compressed array of bit values that is represented as a Boolean value, where true indicates that the bit is open (1), andfalse indicates that the bit is closed (0).
	CaseInsensitiveComparer	Compares two objects for equality, ignoring the case of a string when compared.
	CaseInsensitiveHashCodeProvider	Provides a hash code for an object using a hashing algorithm that ignores the case of a string.
	CollectionBase	Provides an abstract base class for a strongly typed collection.
	Comparer	Compares two objects for equality, where string comparisons are case-sensitive.
	DictionaryBase	Provides an abstract base class for a strongly typed collection of key/value pairs.
	Hashtable	Represents a collection of key/value pairs that are organized according to the hash code of the key.
	Queue	Represents an FIFO collection of objects.
	ReadOnlyCollectionBase	Provides an abstract base class for strongly typed non-generic read-only collections.
	SortedList	Represents a collection of key/value pairs that are sorted by keys and accessed by key and index.
	Stack	Represents a simple last-in-first-out non-generic collection of objects.

Interface

	interface	description
	ICollection	defines the size, enumerator, and synchronization method for all non-generic collections.
	IComparer	exposes a method that compares two objects.
	IDictionary	represents a non-generic collection of key/value pairs.
	IDictionaryEnumerator	enumerates the elements of a non-generic dictionary.
	IEnumerable	exposes an enumerator that supports simple iterations on a non-generic collection.
	IEnumerator	supports simple iterations of non-generic collections.
	IEqualityComparer	defines methods to support equality comparisons of objects.
	ihashcodeprovider	Use a custom hash function to provide a hash code for the object.
	IList	represents a non-generic collection of objects that can be accessed individually by index.

System.Collections.Generic namespaces

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 security and performance than non-generic strongly typed collections.

class

	class	description
	Comparer	Provides a base class for implementations of IComparer generic interfaces.
	Dictionary	Represents a collection of keys and values.
	Dictionary.keycollection	Represents a collection of keys in the Dictionary. This class cannot be inherited.
	Dictionary.valuecollection	Represents a collection of values in Dictionary . This class cannot be inherited.
	Equalitycomparer	Provides a base class for implementations of iequalitycomparer generic interfaces.
	KeyNotFoundException	Specifies the exception that is thrown when the key used to access an element in the collection does not match any key in the collection.
	LinkedList	Represents a doubly linked list.
	LinkedListNode	Represents a node in a linkedlist. This class cannot be inherited.
	List	Represents a strongly typed list of objects that can be accessed through an index. Provides methods for searching, sorting, and manipulating a list.
	Queue	Represents an FIFO collection of objects.
	SortedDictionary	Represents a collection of key/value pairs that are sorted by key.
	Sorteddictionary.keycollection	Represents a collection of keys in the SortedDictionary. This class cannot be inherited.
	Sorteddictionary.valuecollection	Represents a collection of values in sorteddictionary . This class cannot be inherited
	SortedList	Represents a collection of key-value pairs that are sorted by key based on the associated IComparer implementation.
	Stack	Represents a variable-size, last-in-first-out (LIFO) collection of instances of the same arbitrary type.

Interface

	Interface	description
	ICollection	Defines methods for manipulating generic collections.
	IComparer	Defines a method that is implemented by a type that compares two objects.
	IDictionary	Represents a generic collection of key/value pairs.
	IEnumerable	Exposes an enumerator that supports simple iterations on a collection of the specified type.
	IEnumerator	Supports simple iterations on a generic collection.
	IEqualityComparer	Defines methods to support equality comparisons of objects.
	IList	Represents a set of objects that can be accessed individually by index.
