C# Final task just says "Bummer! Try again!" With no error to see where I'm going wrong, please help.

Changed the code, almost there now. Getting this error message: System.ArgumentNullException: Value cannot be null.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            int c = 0;

            while (true) {
              Console.Write("Enter the number of times to print \"Yay!\": ");
              string times = Console.ReadLine();
              try {
                c = int.Parse(times);
                break;
              } catch (FormatException) {
                Console.WriteLine("We only accept whole numbers");
                continue;
              }
            }

            for (int i = 0; i < c; i++) {
              Console.WriteLine("Yay!");
            }

        }
    }
}

EDIT: Fixed!

Program.cs 
using System;

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

            int c = 0;

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

            try {
              c = int.Parse(times);
            } catch (FormatException) {
              Console.WriteLine("You must enter a whole number.");
              return;
            }

            for (int i = 0; i < c; i++) {
              Console.WriteLine("Yay!");
            }

        }
    }
}

Thanks.

Good job. :+1:

Did you figure it out, or find one of my previous posts about this challenge?

I figured it out, similar to your description, thought the user needed to keep entering values if the input was invalid.

Thanks! Happy coding :-)
