It it a collection Object used to store "name = value" pair
information. Collection of similar data.

Answer / sonali

A dictionary is actually just another collection of
Key/Value pairs, just like a HashTable, except that you
declare a type for the Key and Value.
An example of a simple Dictionary object would be something
like:

Dictionary<int, string> newDict = new Dictionary<int,string>();

When you get the key or value, you are given an actual
Object of a specific type. With a HashTable, the Key and
Value are just Objects, meaning they have no type and must
be converted to something in order to be more than just that.
With a dictionary, you can declare the Object types and get
back useful Objects or those types
