c# - Get uniques elements -


i have 

int[] array1 = { 1, 2, 3 }; int[] array2 = { 2, 3, 4 };

using var intersect = array1.intersect(array2);i got 

2 3

but need 

  1   4

can give me advice how can using linq?

array1.union(array2).except(array1.intersect(array2))

explanation:

  1. first calculate set union of 2 sequences: 1, 2, 3, 4
  2. you calculating intersection of sets: 2, 3
  3. you finding set difference between items , intersection: 1, 4
