C# print that many times as user asked ...

So that's the first step of this challenge. Somehow the program shows 52 "Yay's" instead of 5. I have no idea where that 52 came from ...

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {


        static void Main()
        {
            int userNumb = Console.Read();
            int checkVal = 0;

            while (true){
                checkVal += 1;
                Console.Write("Enter the number of times to print \"Yay!\": " + checkVal);
                if (checkVal == userNumb){
                    break;
                }

            }
        }
    }
}

When accepting user-input from ReadLine() the input is stored as a string. You will have to convert it into an integer using int.Parse() (check example below)

class Program
{
    static void Main(string[] args)
    {
        Console.Write("Enter the number of times to print \"Yay!\": ");
        int userNumb = int.Parse(Console.ReadLine()); // You could use int.Parse() like this or do it on the next line

        // I would use a for-loop instead of a while loop for this challenge
        for (int i = 0; i < userNumb; i++)
        {
            Console.WriteLine("Yay"); // You only want to print out the word 'Yay' x-times
        }
    }
}
