When should I use collections in C#?

You should use collections in C# when you need to store multiple items in a single variable, especially when the number of items can change.

What types of collections are available in C#?

C# offers several types of collections, including arrays, lists, dictionaries, and sets, each serving different purposes.

Can you explain when to use a List versus an Array?

Use a List when you need a dynamic size and more functionality, while Arrays are better for fixed-size collections.

What about performance? Are there any differences?

Yes, Arrays are generally faster for accessing elements, but Lists provide more flexibility and ease of use for dynamic data.
