# Except

How do you find elements in an array or list in one and not the other? The Except Linq operation is the way to go.

# Basic example

Take, for instance, I have an array of numbers set1 where they are in increments of 10, following by another array set2 where they are in increments of 5. Then I call the Except method, I should only get the numbers that appear in set1 only and not in set2.

Live example: https://dotnetfiddle.net/Qqiyi2

var set1 = new[] { 10, 20, 30, 40, 50, 60 };
var set2 = new[] { 5, 10, 15, 20, 25, 30, 35 };

var result = set1.Except(set2);

//output: 40, 50, 60
