Project Euler Problem 1 C#

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.

using System;

namespace Dela.Mono.Examples
{
   public class HelloWorld
   {
      public static void Main(string[] args)
      {
         int limit = 1000;
         int counter = 0;
         int sum = 0;
         while (counter < limit)
         {
            if (counter % 3 == 0 || counter % 5 == 0)
            {
               sum = sum + counter;
            }
            
           counter++;
         }
        
         Console.WriteLine("Enter the limit " + sum);
      }
   }
}
