C3 Final Try Catch

Can't be able to get this to work. What is going wrong here?

Program.cs 
using System;

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

            while (times > 0)
            {
              try
              {



              if (times > 0)
              {
                 Console.Write("Yay!");
                 times -= 1;
                 continue;
              }
             }
              catch (FormatException)
              {
                Console.WriteLine("You must enter a whole number.");
                continue;
              }
            }

        }
    }

The "Bummer" I get:

Did you catch FormatException thrown by int.Parse using try and catch?

I guess you didn't find any of the previous posts where I answered this helpful, like this one.

Anyway, here are some hints:

  • Your program must ask for and accept input ONE TIME ONLY (input will not be in a loop)
  • If the input validates, your program will perform exactly as in Task 1
  • If the input does not validate, it will print the error message and exit
  • Validation must be done by exception catching. This means your Parse must be inside a try block.
  • The loop used on success for printing will be after the catch block.
