How can I pass

using System;

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

            int count = int.Parse(input);

            int i = 0;
            while(i < count)
            {
                i += 1;   
                Console.WriteLine("Yay!");
            }
            }
            catch(input != int)
            {
                 Console.WriteLine("You must enter a whole number.");

            }
        }
    }
}
