namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {   
           int i=0;
            Console.Write("Enter the number of times to print \"Yay!\": ");
             var input =Console.ReadLine();
            try{
                var num=double.Parse(input);
                if(num<=0)
                {
                    Console.WriteLine("You must enter a postive num.");
                }
                else
                {
                while(i!=num)
                {
                Console.WriteLine("Yay!");
                    i++;
                }
              }
            }
            catch(FormatException)
            {
            Console.WriteLine("That is not a valid input.");
            }

        }
    }
}

You're using the wrong kind of conversion.

You want to catch when "the user enters a decimal or something that isn’t a number", but your converting the input using double.Parse. That won't cause exceptions for decimals, it will just convert them. You probably want to use int.Parse instead.

Also, the challenges are very picky about output strings, and it wants to see β€œYou must enter a whole number.” on a bad input. But your exception message is "That is not a valid input."
