Why Is My Program Not Working?

I am trying to figure out how to print "Yay!" on the screen as many times as the user asks but my script is just not working. Can anybody tell me where I slipped up?

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
                       Console.Write("Enter the number of times to print \"Yay!\": ");
                String Awnser = Console.Readline;
                    int Number = int.Parse(String Awnser);
                    int Yay = 1
                   Yay = Console.Write("Yay!");
                    while (int Yay < int Number);
                        Yay + 1

        }
    }
}

Try this:

using System;

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

            while (times > 0)
            {
                Console.WriteLine("Yay!");
                times -= 1;
            }
        }
    }
}

Here's a step-by-step explanation of what's going on:

  1. We are getting the input using the Console.ReadLine() function. (Don't forget to use the parentheses when calling a function!)
  2. We convert the input (by default a string and not a number) into a number and store it in a variable called times.
  3. We create a while loop that runs as long as the times variable is greater than zero.
  4. We print out "Yay!", then decrease times by one.

Here's how this works:

"Times" is set to 5 (that's the user input).

C# Prints "Yay!"
"Times" is decreased, now is 4

C# Prints "Yay!"
"Times" is decreased, now is 3

C# Prints "Yay!"
"Times" is decreased, now is 2

C# Prints "Yay!"
"Times" is decreased, now is 1

C# Prints "Yay!"
"Times" is decreased, now is 0

The while loop ends since "Times" is no longer greater than zero.

Good luck! I hope you understand.

Amazing. Thanks For That I was really stuck. I will try out task 2 and see if I can manage. Also is that the only way it could be done or is there other ways to complete this task?

Actually, I believe there's quite a few ways to solve this task :)

For instance, this one is slightly different:

using System;

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

            int i = 0;
            while (i < times)
            {
                Console.WriteLine("Yay!");
                i += 1;
            }
        }
    }
}

However, I think the first approach is simpler/better.
