如何在LINQ中加入常量？

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        int[] numbers = { 1, 2, 3, 4, 5 };
        int constant = 10;

        var result = from n in numbers
                     select n * constant;

        foreach (var item in result)
        {
            Console.WriteLine(item);
        }
    }
}
