16,911 PointsC3 Final Try Catch
Can't be able to get this to work. What is going wrong here?
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
var times = int.Parse(Console.ReadLine());
while (times > 0)
{
try
{
if (times > 0)
{
Console.Write("Yay!");
times -= 1;
continue;
}
}
catch (FormatException)
{
Console.WriteLine("You must enter a whole number.");
continue;
}
}
}
}
}

231,269 PointsI guess you didn't find any of the previous posts where I answered this helpful, like this one.
Anyway, here are some hints:
- Your program must ask for and accept input ONE TIME ONLY (input will not be in a loop)
- If the input validates, your program will perform exactly as in Task 1
- If the input does not validate, it will print the error message and exit
- Validation must be done by exception catching. This means your Parse must be inside a try block.
- The loop used on success for printing will be after the catch block.

Did you catch FormatException thrown by int.Parse using try and catch?
