it has some error

You can return a tuple if you don't want to create a new class

Buddy•5/1/23, 11:52 AM

static (int, int, int) Foo()
{
   return (1, 2, 3);
}

static (int, int, int) Foo()
{
   return (1, 2, 3);
}

But not sure why you'd like to return the same value as the parameters

CzkafekOP•5/1/23, 11:52 AM

How can I use tuples?

CzkafekOP•5/1/23, 11:52 AM

Thinker•5/1/23, 11:52 AM

static (int, int, int) Foo()
{
    return (1, 2, 3);
}

static (int, int, int) Foo()
{
    return (1, 2, 3);
}

var (a, b, c) = Foo();

var (a, b, c) = Foo();

Thinker•5/1/23, 11:53 AM

So in your case,

static (int, int, int) Papier(string user, string komputer, int win, int loss, int draw)
{
    if (komputer == "N")
    {
        Console.WriteLine("Przegrałeś! Wyniki:");
        Console.WriteLine();
    }
    return (win, loss, draw);
}

static (int, int, int) Papier(string user, string komputer, int win, int loss, int draw)
{
    if (komputer == "N")
    {
        Console.WriteLine("Przegrałeś! Wyniki:");
        Console.WriteLine();
    }
    return (win, loss, draw);
}

I see

CzkafekOP•5/1/23, 11:54 AM

thanks

Thinker•5/1/23, 11:54 AM

You could also use a class or a record, but a tuple is probably the easiest here.

CzkafekOP•5/1/23, 11:55 AM

thats record?

Thinker•5/1/23, 11:55 AM

A tuple is not a record

CzkafekOP•5/1/23, 11:55 AM

whats*

Thinker•5/1/23, 11:56 AM

A record would look like this

record PapierResult(int Win, int Loss, int Draw);

static PapierResult(/* ... */)
{
    // ...
    return new PapierResult(win, loss, draw);
}

record PapierResult(int Win, int Loss, int Draw);

static PapierResult(/* ... */)
{
    // ...
    return new PapierResult(win, loss, draw);
}

CzkafekOP•5/1/23, 11:56 AM

thinking one writing another

CzkafekOP•5/1/23, 11:56 AM

hmm okay

CzkafekOP•5/1/23, 11:56 AM

thanks

Translate error?

CzkafekOP•5/1/23, 12:30 PM

for a non-satic field, method, or propert ... an object reference is required

TheRanger•5/1/23, 12:31 PM

well like it says, an object reference is required to access this method

TheRanger•5/1/23, 12:32 PM

it was

static

static

in ur code, did u remove that word?

CzkafekOP•5/1/23, 12:34 PM

nope

CzkafekOP•5/1/23, 12:34 PM

Angius•5/1/23, 12:36 PM

You gave it two return types

Angius•5/1/23, 12:36 PM

int (int, int, int)

int (int, int, int)

Angius•5/1/23, 12:36 PM

Does it return an

int

int

Angius•5/1/23, 12:36 PM

Or an

(int, int, int)

(int, int, int)

CzkafekOP•5/1/23, 12:36 PM

AAAAAA... yes

CzkafekOP•5/1/23, 12:37 PM

now everything works
