Inbuilt Data Structures in C#

C# has a lot of inbuilt Data Structures. Here are two of them −

List

Generic List<T> is a generic collection and the ArrayList is a non-generic collection. The size can be dynamicallyincreased using List, unlike Arrays.

Let us see an example.

We have set the List first −

List<string> myList = new List<string>()

ArrayList

It represents ordered collection of an object that can be indexed individually.

Set an ArrayList as −

ArrayList arr = new ArrayList();
arr.Add(67);
arr.Add(34);
arr.Add(99);
arr.Add(45);
