using System.Collections.Specialized;

class Program
{
    static void Main(string[] args)
    {
        string[] input = Console.ReadLine().Split(' ');
        Player player = new Player(input[0], Int32.Parse(input[1]));
    }
    class Player
    {
        public string _playerName;
        public int playerID;
        public Player(string playerName,int playerIdentifier)
        {
            _playerName = playerName;
            playerID = playerIdentifier;
            Tuple<string, int> playerInfo = new Tuple<string, int>(_playerName,playerID);
        }
    }
}

using System.Collections.Specialized;

class Program
{
    static void Main(string[] args)
    {
        string[] input = Console.ReadLine().Split(' ');
        Player player = new Player(input[0], Int32.Parse(input[1]));
    }
    class Player
    {
        public string _playerName;
        public int playerID;
        public Player(string playerName,int playerIdentifier)
        {
            _playerName = playerName;
            playerID = playerIdentifier;
            Tuple<string, int> playerInfo = new Tuple<string, int>(_playerName,playerID);
        }
    }
}

This may be a beginner question but how do i acces the playerInfo for each Player instance created? how can i put that tuple into a list so whenever i need a player name and his id i can get it from that list

There’s a lot of better options here than using a tuple. What would you be using to access the player? It’s name, id, what?

is not for a game is just for me learning c# and yes his name and his id i want both of them stored somewhere and when i check all the instances of Player Class i can see all of them grouped name with id

All you need is a List<Player> Players. Then do Players.FirstOrDefault(player => player.id == id) I’m on mobile

Uh i don't think i know what that is and how to use it

PPlayboi17

It’s C#s query language It’s basically saying return the first player in this list where the players id matches my provided id If no player in the list matches the id, return default (null)

so when i do List<Player> Players; and i iterate trough all of them i will get all the instances?

Yes

Damn c# is nice

PPlayboi17

If you put all the players in the list It is very nice

No problem

Btw, you should always use (string, int) over Tuple<string, int>

TTony

uh but if i want to iterate over them with a foreach() how do i use that like with a foreach(string player in Players) or how

TThinker

(string, int) is a shorthand for ValueTuple<string, int>, which is a better and more lightweight option to Tuple<string, int>

TTony

2/10/2023

thanks i will keep that in mind

    class Player
    {
        public string _playerName;
        public int playerID;
        public Player(string playerName,int playerIdentifier)
        {
            _playerName = playerName;
            playerID = playerIdentifier;
            List<Player> Players;
        }
    }

    class Player
    {
        public string _playerName;
        public int playerID;
        public Player(string playerName,int playerIdentifier)
        {
            _playerName = playerName;
            playerID = playerIdentifier;
            List<Player> Players;
        }
    }
