C# Queryable Union Method

Perform Union on two sequences using the Queryable Union method.

The following are our arrays.

int[] arr1 = { 29, 40, 15, 55, 70, 30, 90 };
int[] arr2 = { 30, 36, 40, 18, 15, 55, 75 };

Now, get the Union of the arrays using the Union method.

arr1.AsQueryable().Union(arr2);

Example

 Live Demo

using System;
using System.Linq;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      int[] arr1 = { 29, 40, 15, 55, 70, 30, 90 };
      int[] arr2 = { 30, 36, 40, 18, 15, 55, 75 };
      IEnumerable<int> res = arr1.AsQueryable().Union(arr2);
      foreach (int a in res)
      Console.WriteLine("{0} ", a);
   }
}

Output

29
40
15
55
70
30
90
36
