I don't understand why my loop doesn't work anymore in task 2.

My loop stops working when I place the conversion of the entry into integer within Try {} .

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            int counter = 0; 
            string entry = Console.ReadLine();

            while (true)
            {
            try
            {          
            int number = int.Parse(entry);
            counter = counter + 1;

            if(counter > number)
            {
                break;
            }
            Console.WriteLine("Yay!");
            } 
            catch(FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
                continue;
            }
            }    
        }
    }
}

Hi Kimmo,

Please tr below :

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            int counter = 0;
            string entry = Console.ReadLine();

            while (true)
            {
                try
                {
                    int number = int.Parse(entry);
                    counter = counter + 1;

                    if (counter > number)
                    {
                        break;
                    }
                    Console.WriteLine("Yay!");
                }
                catch (FormatException)
                {
                    Console.WriteLine("You must enter a whole number.");
                    continue;
                }
            }

            Console.ReadLine();
        }
    }
}

You need to enter the 'Console.ReadLine()' line at the end of your code. This freezes your console screen to view the results until you hit the return key.

Hope that helps. All the best!

Hi Kimmo,

I tried out the code you supplied and I couldn´t get an error (it displayed "Yay!" as many times as I entered an integer/number) and your conversion from string to int happens within the try-block. If you have an issue with above code, I would suggest clearing the cache of your browser and try writing the exercise once more. I've had a few tasks act up as it seems to conflict with cached data now and then. Let me know if this fixed your error.
