I have seen some solution here for the same problem, this and this I have found better ways to solve this problem. I just want to know how good or bad my code and way of approaching this problem is.

using System;

public class Program
{
    public static void Main()
    {
        int sum = 0;
        for (int i = 0; 3 * i < 1000; i++)
        {
            sum += 3 * i;

            if (5 * i < 1000 && (5 * i) % 3 != 0)
            {
                sum += 5 * i;
            }
        }
        Console.WriteLine(sum + "");
    }
