I'm using the same code in the Visual Studio and also in the Treehouse workspace and I don't have the error.

The error System.ArgumentNullException appears when I try to check my work. I don't have the same error in treehouse workspace and the program is doing exactly what the excercise is asking. Can someone review my code please?

Program.cs 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Yay();
        }
        static void Yay()
        {
            bool error = true;
            int check = 0;

            while (error)
            {
                bool keepGoing = true;

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

                string entry = Console.ReadLine();

                while (keepGoing)
                {
                    try
                    {
                        int times = int.Parse(entry);

                        if (check < times)
                        {
                            Console.WriteLine("Yay!");
                            check += 1;
                        }
                        else
                        {
                            keepGoing = false;
                        }
                        error = false;
                    }
                    catch (FormatException)
                    {
                        Console.WriteLine("You must enter a whole number");
                        keepGoing = false;
                        continue;
                    }
                }
            }
        }
    }
}

This is what I did in the challenge and it passed:

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            try{
              Console.Write("Enter the number of times to print \"Yay!\": ");
              var yayCount = Console.ReadLine();
              var count = 0;
              if(Int32.Parse(yayCount) < 0){
                Console.Write("You must enter a positive number.");
              }
              else{

                while(count < Int32.Parse(yayCount)){
                  Console.Write("Yay!");
                  count++;
                }

              }

            }
            catch(FormatException formatException){
              Console.Write("You must enter a whole number.");
            }

        }
    }
}
