Lists (Dynamic Arrays)

• Lists are similar to CSharp Arrays but they have dynamic size (Useful when we don’t know the space required beforehand)
• List is a Generics type. All generic type uses <...> in its declaration
• Most of the times in newer code Lists are used instead of Arrays

List<int> primeNumbers = new List<int>();
 
// Methods
primeNumbers.Add(10);
Console.WriteLine(primeNumbers.Count);
primeNumbers.IndexOf(4);
primeNumbers.LastIndexOf(3);
primeNumbers.Remove(4);

The System.Collections.Generic namespace needs to be imported for using Lists and other generic datatype
