Question

Given an array like {‘one two’, ‘three four five’}, how’d you calculate the total number of words contained in it using LINQ?

Answer 1

Or if you want to use the C# language extensions:

var words = (from line in new[] { 'one two', 'three four five' }              from word in line.Split(' ', StringSplitOptions.RemoveEmptyEntries)              select word).Count();
