[Solved] Linq – Where().Where() is AND or OR?

by


This is the same as doing two separated operations:

var numbers = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

var biggerThanThree = numbers.Where(x => x > 3); // [4, 5, 6, 7, 8, 9, 10]

var smallerThanSeven = biggerThanThree.Where(x => x < 7); // [4, 5, 6]

I’m not going into lazy execution here, to keep things simple.

But the second .Where operates on the list already filtered by the first .Where, so it acts as an AND
