C# Linq Intersect Method

Find common elements between two arrays using the Intersect() method.

The following are our arrays −

int[] val1 = { 15, 20, 40, 60, 75, 90 };
int[] val2 = { 17, 25, 35, 55, 75, 90 };

To perform intersection.

val1.AsQueryable().Intersect(val2);

Let us see the entire example.

Example

 Live Demo

using System;
using System.Collections.Generic;
using System.Linq;
class Demo {
   static void Main() {
      int[] val1 = { 15, 20, 40, 60, 75, 90 };
      int[] val2 = { 17, 25, 35, 55, 75, 90 };
      IEnumerable<int> res = val1.AsQueryable().Intersect(val2);
      Console.WriteLine("Intersection of both the lists...");
      foreach (int a in res)
      Console.WriteLine(a);
   }
}

Output

Intersection of both the lists...
75
90
