The use of input validation on the try and catch exception

Add input validation to the below program by printing "You must enter a whole number." if the user enters a decimal or something that isn’t a number.

Program.cs
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {

            Console.Write("Enter the number of times to print \"Yay!\": ");
            string input = Console.ReadLine();     

           try
           {
            int count = int.Parse(input);
           }

            int i = 0;
            while(i < count)
            {
                i += 1;   
                Console.WriteLine("Yay!");
            }

                catch (FormatException)

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

        }
    }
}

Try putting the loop inside the "try" block. There should be no code between the "try" block and the "catch".
