Intersect Method in C#

Use the Intesect method to get the common elements −

Create lists −

var list1 = new List{99, 87}; var list2 = new List{56, 87, 45, 99};

Now, use the Intersect() method to get the common elements from the above list −

list1.Intersect(list2);

Here is the complete code −

Example

 Live Demo

using System.Collections.Generic; using System.Linq; using System; public class Demo {    public static void Main() {           // two lists       var list1 = new List<int>{99, 87};       var list2 = new List<int>{56, 87, 45, 99};       // common values       var res = list1.Intersect(list2);       foreach(int i in res) {          Console.WriteLine(i);       }    } }

Output

99 87
