Last three challenges are tough..

I'm having a tough time answering these last three challenges... help please!

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
        var callTotal = 0.0;

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

            var entry = Console.ReadLine();

            if (entry.ToLower = "Yay!")
            {
              break;
            }
        }


        }
    }
}

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            var count = 0;

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

            try
            {
                var numberOfTimes = int.Parse(entry);
                if(numberOfTimes > 0) {
                while (count < numberOfTimes)
                {
                    Console.WriteLine("Yay!");
                    count++;
                }
                } else {
                Console.WriteLine("You must enter a positive number.");
                }
            }
            catch(FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

namespace is treehouse.codechallenges

start count at 0. prompt user to type number of times of saying yay. store variable entry try catch is if else

try(if) store variable int.Parse "integer becomes a number"; loop yay the number of times. Else(false) print "you have to enter a whole number."

If else nested is to test if it's positive. So if positive do loop. If not throw else print please give me positive number
