What are the common collections in C#?
In C#, common collections include List, Dictionary, HashSet, Queue, and Stack. Each serves different purposes.
Can you explain the difference between List and Array?
Sure! A List is dynamic and can grow or shrink in size, while an Array has a fixed size once initialized.
When should I use a Dictionary?
Use a Dictionary when you need to store key-value pairs for fast lookups based on unique keys.
What is a HashSet used for?
A HashSet is used to store unique elements and is great for scenarios where you need to ensure no duplicates.
Can you give an example of using a Queue?
Certainly! A Queue is used in scenarios like task scheduling, where you process items in a first-in, first-out order.
