I don't know what's wrong with my code.

The code is below. If someone know about this mistake, please let me know. Thank you!

Program.cs
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            int i = 0 ;
            int num;
            Console.Write("Enter the number of times to print \"Yay!\": ");

            num = Convert.ToInt32(Console.ReadLine());

            while (i <= num)
            {
                Console.WriteLine("Yay!");
            }

        }
    }
}

You forgot to decrement your num variable by 1 each time the loops run at the current state you got an loop which runs infinitely. Also you can declare and assign the variable num in one line of code to safe space ^^ And in the while statment use num > 0 instead of >= you want to stop at 0 :)

  static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            int i = Convert.ToInt32(Console.ReadLine());
            while(i > 0){
                 i--;
                 Console.Write("Yay!");
            }
        }
