When do I have to use dictionaries in c#

Question

Please can someone tell me the situations for use of dictionaries or use of dictionaries

Answer 1

When you want to get quick access to the characteristics of a particular object 🤔
Close relation between the keys and values helps a lot when arrays make it difficult 😄

Simple implementation:
Make a code that provides the respective arrays of all the factors of numbers from 1 to 50!
