What are the different collection types in C#?
C# offers several collection types, including arrays, lists, dictionaries, and sets. Each serves different purposes.
Can you explain the difference between a List and an Array?
Sure! An Array has a fixed size and can store elements of the same type, while a List is dynamic and can grow or shrink.
When should I use a Dictionary?
Use a Dictionary when you need to store key-value pairs for fast lookups. It's great for scenarios where you need to access data by a unique key.
What about HashSet? How is it different from List?
A HashSet is used to store unique elements and does not allow duplicates, while a List can contain duplicate values.
