Having trouble with catching the exception on the final challenge

It says "Bummer. Try again." When I run it in workspaces it works perfectly.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            while (true) {
                try {
                    var doIt=Int32.Parse(Console.ReadLine());
                    Console.Write("Enter the number of times to print \"Yay!\": ");
                    while (doIt!=0) {
                        Console.WriteLine("Yay!");
                        doIt-=1;
                    }
                }
                catch (SystemException) {
                    Console.WriteLine("You must enter a whole number.");
                    continue;
                }

                break;    
            }
        }
    }
}

Hi Bosco,

For this challenge you don't need a loop. So you can take out the while, break, and continue statements. The program should just end if they don't enter a number rather than continually prompt for a number.

The other issue is that you should be a catching a FormatException

I'm not sure if it will affect the challenge but the ReadLine should be after the Write so that the user knows what they're supposed to enter.
