Deferred Query Execution

 



using System;

using System.Linq;



class MainClass {

    static double Square(double n) {

        return Math.Pow(n, 2);

    }

    public static void Main() {

        int[] numbers = { 1, 2, 3 };

        var query = from n in numbers select Square(n);

        foreach (var n in query)

            Console.WriteLine(n);

    }

}
