C# C# Basics (Retired) Perfect Final

Problem with the Final of C# Basics(the second challenge of three). I tested my code on Visual Studio and it seemed OK.

When I ran my code in Visual Studio it seemed to give me the correct results for the challenge yet it doesn't pass on the Final. Any help would be appreciated. Thanks.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            while (true)
            {
                int result = 0;
                Console.Write("Enter the number of times to print \"Yay!\": ");
                try
                {
                    result = int.Parse(Console.ReadLine());
                }
                catch (FormatException)
                {
                    Console.WriteLine("You must enter a whole number.");
                }
                int counter = 1;
                while (counter < result + 1)
                {
                    Console.WriteLine("yay");
                    counter++;
                    if (counter == result + 1)
                    {
                        Console.ReadLine();
                        Environment.Exit(0);
                    }
                }
            }

        }
    }
}

:warning: Be careful about testing a challenge in an external REPL or IDE.

If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.

In this case, you have added an extra loop that prevents the program from ending if bad values are entered..

A program that follows the challenge instructions will only ask for input one time, and either print "Yay!"s or an error message. But either way it should end.
