Bummer! I entered 5, but saw Yay! printed 1 time. Did you modify the while loop?

Hello,

I have commented throughout the code. My while doesn't appear to be repeating. Have a I declared variables incorrectly? I'm grasping at straws here. Just rewatched the try catch, heading back to the while videos.

Thanks in advance,

Jude

Program.cs 
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();
            //Ask user to input how many times they want to see yay. Convert that input into a string.

            int count = int.Parse(input);
            //New variable called count that is the user input converted into an integer.
            int i = 0;
            while(i < count)
            i += 1;   
            Console.WriteLine("Yay!");
            //Setting variables for the while to work. Int is set to 0. Somehow as the while runs the code
            //is able to remember the last state of i and ad 1 to it. Increasing until the while is not true.
            }
            catch(Exception)
            {
            Console.Write("You must enter a whole number.");
            //If the user inputs something other than a whole number we will catch it here and send them
           // back to the start of the try. My assumption is that is built into the Try/Catch method.     

            }
        }
    }
}
