1,521 PointsI'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?
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;
}
}
}
}
}
}

29,567 PointsThis 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.");
}
}
}
}
