Project Euler - Question 1

I'm playing around with Project Euler to increase my C# skills. The first question in is:

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

Here is my solution in a C# console application:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ProjectEuler1
{
    class Program
    {
        static void Main(string[] args)
        {
            int result = 0;
            for (int i = 1; i < 1000; i++)
            {
                if (((i % 3) == 0 || ((i % 5) == 0))) {
                result += i;
                }
            }
            Console.WriteLine("answer is:" + result);
            Console.ReadLine();
        }
    }
}
