What is the difference between a list and an array in C#?

An array stores a fixed-size sequential collection of elements of the same type, whereas list is a generic collection.

To define a List −

List<string7gt; myList = new List<string>();

To set elements in a list, you need to use the Add method −

myList.Add("Audi");
myList.Add("BMW");
myList.Add("Chevrolet");
myList.Add("Hyundai");

To define Arrays −

int[] arr = new int[5];

To initialize and set elements to Arrays −

int[] arr = new int[5] {23, 14, 11, 78, 56};
