Union Method in C#
The Union method gets the unique elements from both the lists.
Let us set two lists −
var list1 = new List<int>{12, 65, 88, 45}; var list2 = new List<int>{40, 34, 65};
Now get the union of both the lists −
var res = list1.Union(list2);
The following is the example −
Example
using System.Collections.Generic; using System.Linq; using System; public class Demo { public static void Main() { // two lists var list1 = new List<int>{12, 65, 88, 45}; var list2 = new List<int>{40, 34, 65}; // finding union var res = list1.Union(list2); foreach(int i in res) { Console.WriteLine(i); } } }
Output
12 65 88 45 40 34
