On the C# Basic final challenge task part 2, my code does all the challenge ask me to do but it is saying it isn't.

Question

The challenge says to let the user input how many times to say "Yay!", then display it. If the user inputs anything that isn't a whole number, tell them "You must enter a whole number." and prompt them to try again. I have done all this in my code but it is telling me Task 1 is no longer working when it is!

Program.cs

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {

            var truth = true;
            while (truth)
            {

                try
                {

                    Console.Write("Enter the number of times to print \"Yay!\": ");
                    string entry = Console.ReadLine();


                    int DisplayNumber = int.Parse(entry);

                    if (DisplayNumber =< 0)
                    {
                        Console.WriteLine("You must enter a whole number.");
                        continue;
                    }

                    else
                    {
                        for (int x = 0; x < DisplayNumber; x++)

                        {

                            Console.WriteLine("\"Yay!\"");
                            truth = false;

                        }

                    }

                    Console.ReadKey();
                }


                catch (FormatException)
                {
                    Console.WriteLine("You must enter a whole number.");
                    continue;

                }
            }
            Console.WriteLine("PEACE!");
            Console.ReadKey();
        }
    }
}

Take another look at this code bit:

if (DisplayNumber =< 0)
    {
        Console.WriteLine("You must enter a whole number.");
        continue;
    }

Is it really looking for a whole number?

Let me put it this way, 1.2 is greater than 0, but is it a whole number?

Furthermore look at the int.tryparse method.

I would try something like this

if (int.TryParse(entry)
{
    for (int x = 0; x < entry; x++)
    {
        Console.WriteLine("\"Yay!\"");
        truth = false;
    }
} else {
    Console.WriteLine("You must enter a whole number.");
    continue;
}

Your program deviates from the instructions.

This has been a topic of many previous questions, but I'll repost the info here:

People often over-think this one and get too creative, and their answer is rejected for a variety of reasons (some which don't seem to make any sense).

Here are the secret "rules" you must follow for success on this one:

Your program must ask for and accept input ONE TIME ONLY
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. There are other perfectly good methods that can be used for validation, but they will not pass this challenge

It looks like you have an extra loop that is violating the first and third "rule", an extra output displaying "PEACE!", a "ReadKey" that also voilates rule 1 and prevents the program from exiting as expected, and "=<" is not a valid comparison operator (you probably intended "<=").
