✅ Tuples in classes

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

Connor•2y ago

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?

TonyOP•2y ago

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

Connor•2y ago

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

TonyOP•2y ago

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

Connor•2y ago

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)

TonyOP•2y ago

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

Connor•2y ago

Yes

TonyOP•2y ago

Damn c# is nice

Connor•2y ago

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

TonyOP•2y ago

thanks man

Connor•2y ago

No problem

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

TonyOP•2y ago

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

Thinker•2y ago

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

TonyOP•2y ago

thanks i will keep that in mind

Iterate over a tuple?

TonyOP•2y ago

    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;
        }
    }

how do i iterate over Players

Thinker•2y ago

foreach (Player player in Players) { ... }

TonyOP•2y ago

oh ok yeah i was using foreach (Player in Players) { ... }

Thinker•2y ago

you have to specify the type, yeah
