Why I always got wrong in Challenge Task 3?

In fact, I'v pasted this code to Visual Studio 2017. It can run well. But always got wrong in Challenge Task 3 of 3. It always shows that Oops! It looks like Task 2 is no longer passing!

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

                if (count < 0)
                {
                    Console.WriteLine("You must enter a positive number.");
                    continue;
                }

                int i = 1;
                while (i <= count)
                {
                    Console.Write("Yay!");
                    i++;
                }
                break;
            }
            catch (FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
                continue;
            }
        }
    }
}

}

Program.cs
using System;

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

                    if (count < 0)
                    {
                        Console.WriteLine("You must enter a positive number.");
                        continue;
                    }

                    int i = 1;
                    while (i <= count)
                    {
                        Console.Write("Yay!");
                        i++;
                    }
                    break;
                }
                catch (FormatException)
                {
                    Console.WriteLine("You must enter a whole number.");
                    continue;
                }
            }
        }
    }
}

This challenge only needs one loop. You have an extra outer loop that prevents the program from ending when bad values are entered.

A program built according to the instructions will prompt and accept input one time, and based on the input it will either print "Yay!"s or an error mesage. Either way, it should end.

Thanks!! I got it!!
