PROJECT EULER #1

Link to Project Euler problem 1

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.

Not much to say about this one..

using System;

namespace ProjectEuler
{
   class Program
   {
       static void Main(string[] args)
       {
           //Problem 1
           int sum=0;
           for (int i = 1; i < 1000;i++ )
           {
              sum += i%3 == 0  i%5 == 0 ? i : 0;
           }
           Console.WriteLine("{0}",sum);
       }
   }
}
