I cannot get passed this last task. Hopefully someone can see why the code is rejected and tell me how i can make this work.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
try
{
int numberOfTimes = int.Parse(Console.ReadLine());
while ( numberOfTimes < 0 )
{
Console.WriteLine("You must enter a positive number.");
Console.Write("Enter the number of times to print \"Yay!\": ");
numberOfTimes = int.Parse(Console.ReadLine());
}
for (int i = 0; i < numberOfTimes; i++)
{
Console.WriteLine("Yay!");
}
}
catch (FormatException)
{
Console.WriteLine("You must enter a whole number.");
}
}
}
}

There should not be a loop to get input more than once.

4,003 PointsThanks for your answer.
I fixed the problem by declaring a string variable to which i assigned the result of Console.ReadLine(). As seen in: https://teamtreehouse.com/community/my-c-basics-final-quiz-13-code-works-in-visual-studio-but-wont-pass-the-quiz-whats-wrong
Regarding your comment that there shouldn't be a loop to get input more than once, you're absolutely right. I removed it.
