C# program to print all the common elements of two lists

CsharpProgrammingServer Side Programming

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 −

Example

 Live Demo

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);
      }
   }
}

Output
