❔ Return two values from a method

So im making a blackjack game and i have a method where the player or the dealer draws cards. I want to implement aces and i thought that making a boolean and checking if the drawed card is an ace is the best method but i dont know how to return 2 values from a method. I researched it and i found 3 things: out, ref and tuples. Didnt understand none of them. Can someone help me? Also any other advice on the code would be greatly appreciated!

Cards should simply be objects

can return a tuple then. Looks like public (bool foo, int bar) MethodName()...

how do i return them to the main?

Call the method

vl4doOP•2y ago

like dealerHand = ... hasAce = ....

var thing = MethodName();
var foo = thing.foo;
var bar = thing.bar;

var thing = MethodName();
var foo = thing.foo;
var bar = thing.bar;

Or shorter,

var (foo, bar) = MethodName();

var (foo, bar) = MethodName();

so my code should look like var (dealerHand, dealerHasAce) = DrawCard(dealerHasAce, "dealer", dealerHand, cards); ? sorry idk how to do this rectangle around the code

not quite you can't pass the values in if you are also getting them out like that or rather, you can, if they already exist before but then you drop the var

they do so just (dealerHand, dealerHasAce) = DrawCard(dealerHasAce, "dealer", dealerHand, cards); ?
