C# C# Basics (Retired) Perfect Final

I have looked at several "Final" Questions but am still stuck on challenge task 2 of "Final".

My 1st code passes challenge task 1, but even looking at the community I can't figure out how to make my second code pass task 2. Both of my codes are below. The problematic one is second.

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            string input = Console.ReadLine();

            try
            {
                int count = int.Parse(input);

                int i = 0;
                while(i < count)
                {
                    i += 1;   
                    Console.WriteLine("Yay!");
                }
            }

            catch(FormatException)
            {
              Console.WriteLine("You must enter a whole number.");

            }
        }
    }
}

Task Two:

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            string input = Console.ReadLine();
            int count = int.Parse(input);
            int test = int.Parse(input);
            while(true)
            {
                if(test < 0)
                        {
                                Console.WriteLine("You must enter a positive number.");
                                break;

                        } 
                else
                {


                    try
                    {



                        int i = 0;
                        while(i < count)
                        {
                            i += 1;   
                            Console.WriteLine("Yay!");
                        }
                    }

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

Thank you anyone who helps.

First of all, you are creating an infinite loop with the while(true) statement. Be careful when using loops without a condition that will never be false, because the only way that the loop will end is if you put the break keyword somewhere inside the loop; otherwise, this will run forever. Secondly, you don't need the loop for this challenge. The other thing Task one is no longer passing. This is happening because your try{} block has to contain all your code, and you moved it inside the else in the loop. This code passed for me.

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            try{
            Console.Write("Enter the number of times to print \"Yay!\": ");
            string input = Console.ReadLine();

            int count = int.Parse(input);
            if(count > 0){
                int i = 0;
            while(i < count)
            {
                i += 1;   
                Console.WriteLine("Yay!");
            }
            }
                else{
                    Console.WriteLine("You must enter a positive number.");
                }

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

Thank you for your response. I followed your code and was able to see, line by line, my mistakes.
