Understanding the C# List<T>

• The List<T> is a collection of strongly typed objects that can be accessed by index and includes methods for sorting, searching, and modifying the list.
• It is the generic version of the ArrayList, found within the System.Collections.Generic namespace.
• The List<T> performs faster and is less error-prone than the ArrayList.
• Because it is a generic collection, you must specify a type parameter for the data it stores.

Creating a List and Adding Elements

List<int> primeNumbers = new List<int>();
primeNumbers.Add(1); // Adding elements using Add() method
primeNumbers.Add(3);
primeNumbers.Add(5);
primeNumbers.Add(7);

Using Collection Initializer Syntax

var bigCities = new List<string>()
{
