653 PointsI'm running it fine in the Workspace but it's not working in the Assessment: System.NullReferenceException error.
Hi! I was trying to complete the final step on the C# Basic course and I've written this code which is working in the Workspace without any problem, but when I try to "Preview" or "Recheck work" in the assessment, I get an error saying System.NullReferenceException.
Can anybody check it for me? I'm quite lost and it's the second code I'm getting this error with for the same exercise. I was trying it with a for instead of while for the loop and I've had the same situation: it was working in the Workspace but not in the Assessment window.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
while (true)
{
Console.Write("Enter the number of times to print \"Yay!\": ");
var entry = Console.ReadLine();
if (entry.ToLower() == "quit")
{
Console.WriteLine("Goodbye!");
break;
}
else
{
try
{
int count = int.Parse(entry);
if (count <= 0)
{
Console.WriteLine("You must enter a positive number");
}
else if (count > 0)
{
int n = 1;
while (n <= count)
{
Console.WriteLine("Yay!");
n++;
}
}
}
catch (FormatException)
{
Console.WriteLine("You must enter a valid number");
}
}
}
}
}
}

231,236 PointsIt's always a good idea to stick with the challenge instructions.
Looks like you figured out that the extra additions were a problem. People often over-think this one and get too fancy.
The secret to challenge success is to do everything the challenge asks for, but nothing extra.
