C# Basics Code Challenge: Final - Task 2 of 3 - "Bummer! Your code took too long!"

There is nothing wrong with your code, in fact it's quite through, but that is part of the problem. Challenges on Treehouse are often designed with very specific solutions in mind, and only designed with certain features in mind. The code you have written does more than what the challenge expects it to do, and thus it breaks the code checker.

Using a while loop to reprompt a user for an answer when they input something invalid makes perfect sense, but it is not something the task instructed you to do, and it is in fact not something the task expects you to do. The code checker that verifies the code for this challenge is only setup to provide input to the method once. Prompting it for input multiple times will lead to the code being rejected.

When the instructions asked you to catch the FormatException and print out a message that is in fact all they expected you to do, nothing beyond that. So if you remove all of your looping and just keep the exception handling like this:

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            var yayRunningTotal = 0;

            Console.Write("Enter the number of times to print \"Yay!\": ");
            var entry = Console.ReadLine();
            try
            {
                var yayLimit = int.Parse(entry);
                while (yayRunningTotal < yayLimit)
                {
                    yayRunningTotal += 1;
                    Console.WriteLine("Yay!");
                }

            }
            catch (FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

Then your code will be accepted. Keep in mind that the same things applies to task 3. Task 3 also involve adding some input validation, but there also you are not meant to do anything beyond printing a message.

And again, don't take this as a fault in your code or coding skills, your solution is actually very good. It's just one the challenge is not setup to handle.
