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
