I just have an issue here.

Here's the question-"Add input validation to your program by printing “You must enter a whole number.” if the user enters a decimal or something that isn’t a number. Hint: Catch the FormatException." Please find out what I have done wrong here.

Thanks

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            string number = Console.ReadLine();
            try {
            int number1 = int.Parse(number);
            int numberone = 0;

            bool cycle = true;
            while (cycle == true) {
                Console.WriteLine("Yay!");
                numberone = numberone + 1; 
                if (numberone == number1) {
                     break;
                }
             }
            } catch(FormatException) {

                    Console.WriteLine("You must enter a whole number");

            }

        }
    }
}

Hello!

Have you tried using both , and . to define decimals?

Usually you can type a decimal as 3.50, but it's also correct to type it as 3,50. I mean you can type them using both a comma and a point.

Sorry, I read your question wrong at first.

The boolean variable is not necessary. We could simplify that into

while (true) {
    Console.WriteLine("Yay!");
    numberone = numberone + 1; 
    if (numberone == number1) {
        break;
    }
}

But we can also remove the if statement inside and put the condition inside the while statement. Instead of checking if they are equal and break the iteration, we can iterate as long as the two values are different:

while (numberone != number1) {
    Console.WriteLine("Yay!");
    numberone = numberone + 1; 
}

Changing this made it work for me.
