C# C# Basics (Retired) Perfect Final

C# Basics, Final Challenge Task 3 throws Exception

I cannot get passed this last task. Hopefully someone can see why the code is rejected and tell me how i can make this work.

Program.cs
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            try 
            {
                int numberOfTimes = int.Parse(Console.ReadLine());

                while ( numberOfTimes < 0 )
                {
                    Console.WriteLine("You must enter a positive number.");   
                    Console.Write("Enter the number of times to print \"Yay!\": ");
                    numberOfTimes = int.Parse(Console.ReadLine());
                }

                for (int i = 0; i < numberOfTimes; i++)
                {
                    Console.WriteLine("Yay!");
                }
            }
            catch (FormatException) 
            {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

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

There should not be a loop to get input more than once.

Thanks for your answer.

I fixed the problem by declaring a string variable to which i assigned the result of Console.ReadLine(). As seen in: https://teamtreehouse.com/community/my-c-basics-final-quiz-13-code-works-in-visual-studio-but-wont-pass-the-quiz-whats-wrong

Regarding your comment that there shouldn't be a loop to get input more than once, you're absolutely right. I removed it.

Converting the input to a value on the same line shouldn't cause any problems. It's not really necessary to have a separate string value.
