Need help with getting past this lesson, please

I need a refresher, before proceeding to this lesson, since I have been away.

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();

            int count = int.Parse(input);

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

It doesn't look like you've written any code yet, that seems to be the code as the challenge provides to start with. Please describe the problem you're having, and show the code you entered when you encountered the issue.

First of all the challenge is of exception handling and it is done by try catch block. The exception is caused by the this line: int count = int.Parse(input); So you have to put this line in try block with the while loop, as the while loop also contains the count variable. And catch the exception by doing this: Catch(ExceptionName){code you want to display}
