Don't know why this code is not passing the test. There are no compiler error messages. Program uses a loop to ensure valid data is entered. Code does not seem to satisfy the test. Why?
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
int timesToPrint = 0;
while(true)
{
var x = Console.ReadLine();
try
{
timesToPrint = int.Parse(x);
if(timesToPrint < 0)
throw new FormatException("Negative value entered.");
// Print Yay!
while(timesToPrint > 0)
{
Console.WriteLine("Yay!");
timesToPrint--;
}
break;
}
catch(FormatException e)
{
Console.WriteLine("You must enter a whole number.");
continue;
}
catch(Exception ex)
{
Console.WriteLine("You must enter a whole number.");
continue;
}
}
}
}
}

Console.Write("Enter the number of times to print \"Yay!\": ");
var countString = Console.ReadLine();
int count;
Int32.TryParse(countString, out count);
while(count > 0) {
Console.Write("Yay!");
count--;
}
