Needing help again....

Question

I feel somewhat dumb for having to ask for help like 3 times today but this will be the last. I've used while, try and catch and still don't know if that is even what I am meant to be doing

Program.cs

using System;

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

             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");
                continue;
             }
             }
        }
    }
}

Try take it step by step:

Wrap all of the code contained in the Main method in a try/catch block

try
{
    // code goes here
}
catch () // The catch block should catch FormatException exceptions
{
    //Inside of the catch block, output to the console the message "You must enter a whole number."
}

Looks like your catch block is inside your try block - maybe try rewatch the video about try/catch if you have problems understanding how it's working :-)

Also, the try/catch should not be wrapped in a while-loop :-) Just take the original code and put it inside the try block :-)

Anyway, I hope this helps :-)
