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};
