Hi,
Collection classes are defined as part of the System.Collections or System.Collections.Generic namespace.
Collections are data structures that holds data in different ways for flexible operations.
There are collection classes in C# like ArrayList, HashTable, LinkedList, Stack, Queue, etc.

Hi,
Collection class defines all the data type related to data structure like ArrayList, List<> etc. as these data types are different from those of Ints and Strings, in the way that they are dynamic by nature as far as allocation of memory is concerned.
For more reading, refer below to MSDN:

Hope it'll help you.

As the name suggest, collection class is used for storing and retriving multiple variables. These classes provide support for stacks, queues, lists, and hash tables. Arraylist are also member of this class.
This class is defined under System.Collections.Generic namespace.

These Collection Classes provides type-safety at compile-time.
These Collection Classes are derive from the interfaces ICollection, IComparer, IEnumerable, IList, IDictionary, and IDictionaryEnumerator and their generic equivalents.
These Collection classes are avilable in as part of the System.Collections and System.Collections.Generic namespaces.
using System.Collections;
using System.Collections.Generic;
LinkedList<string> ll = new LinkedList<string>();
ArrayList arrLs = new ArrayList();
arrLs.Add(10);
arrLs.Add(20);
List<string> a = new List<string>();
Hashtable h = new Hashtable();
Dictionary<int, string> d = new Dictionary<int, string>();
