When i run this application, it just displays "Please choose rock, paper or scissors" for as many times as the user inputs for the numPlays. I also need to store the results in an array and display all of the outcomes at the end. Can someone please point me in the right direction?

What I have tried:

Main Class:

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Game rps = new Game();
            rps.start();
            rps.gameStart();
        }
    }
}

Game Class:

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Game
    {
        string name;
        int numPlays;
        int game;

        public void start()
        {
            Console.WriteLine("Welcome to rock, paper, scissors");
            this.userSettings();
        }

        public void userSettings()
        {
            Console.WriteLine("What is your name: ");
            name = Console.ReadLine();

            Console.WriteLine("How many games would you like to play?: ");
            Int32.TryParse(Console.ReadLine(), out numPlays);
            if (numPlays < 10)
            {
                while (numPlays % 2 == 0)
                {
                    Console.WriteLine("\nNumber is not odd try again.");
                    Console.WriteLine("How many games would you like to play?: ");
                    Int32.TryParse(Console.ReadLine(), out numPlays);
                }

                Console.ReadLine();
            }

            else
            {
                Console.WriteLine("Please insert number less than or equal to 9");
                this.userSettings();
            }


        }

        public void gameStart()
        {

        for(game = 1; game <= numPlays; game++)

            Console.WriteLine("Please choose Rock, Paper, or Scissors");
            string userSelection = Console.ReadLine();

            Random r = new Random();
            int computerSelection = r.Next(4);

            if (computerSelection == 1)
            {

I would suggest using lookup tables to both find and store the results.

Learning programming is like learning to drive a car. When you learn how to drive a car, you are required to learn all road signs before putting your hands on the wheel, no matter what. It is the same for programming, there is a set of techniques you need to learn before starting your own projects.

My advices:
- Forget this project for now.

- Learn the language by reading documentation.

- Follow tutos to get familiar with common techniques and concepts.

- Learn the debugger as soon as possible, it is a great tool to learn how your code behave.
Debugger - Wikipedia, the free encyclopedia[^]
Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]

- Learn some analyze methods/techniques, , Dijkstra Top-Down method is a good start.
https://en.wikipedia.org/wiki/Top-down_and_bottom-up_design[^]
https://en.wikipedia.org/wiki/Structured_programming[^]
https://en.wikipedia.org/wiki/Edsger_W._Dijkstra[^]
https://www.cs.utexas.edu/users/EWD/ewd03xx/EWD316.PDF[^]

Remember the exercises and little projects of tutos are not here to make something useful, they are here to teach you programming.

Advice: add a display of computer choices and you will see that your program is completely wrong.

C#

Random r = new Random();
int computerSelection = r.Next(4);
Console.WriteLine(computerSelection);
Console.WriteLine("\n");
