Firstly create the two lists −
List list1 = new List() {40, 20, 60, 3, 55}; List list2 = new List() {20, 70, 55, 80};
To find the common elements, use the Intersect −
list1.Intersect(list2)
The following is the complete code to find the common elements between the two lists −
using System; using System.Linq; using System.Collections.Generic; namespace Demo { class Program { static void Main(string[] args) { List list1 = new List() {40, 20, 60, 3, 55}; List list2 = new List() {20, 70, 55, 80}; Console.WriteLine("Common elements:"); foreach(int value in list1.Intersect(list2)) Console.WriteLine(value); } } }
Common elements: 20 55
