Pointing Problems

Question

private void button1_Click(object sender EventArgs e) { Card Card1 = new Card(); Card Card2 = new Card(); Card1.Value = 3; Card1.Suit = 3; Card2 = Card1; Card2.Suit = 2; } public class Card { public int Suit; public int Value; public Card() { Suit = 0; Value = 0; } } I step through the Button1 code and any changes on Card2 are updated across to Card1 like they were the same or if card2 were simply pointing to card1. What have I done wrong? THanks

Sorry for the Delay here is the fixed Code: private void button1_Click(object sender EventArgs e) { Card Card1 = buildBaseCard(); Card Card2 = buildBaseCard(); Card2.Suit = 2; } private Card buildBaseCard() { Card baseCard = new Card(); baseCard.Value = 3; baseCard.Suit = 3; return baseCard; } public class Card { public int Suit; public int Value; public Card() { Suit = 0; Value = 0; } }

Ok so how do i actually duplicate it rather than point to it? So that Card2 is entirely seperate to Card1 but starts off with the same values?

well the problem is in the following Card2 = Card1 when you did that you actually told the compiler to put a pointer from Card1 to Card2 meaning that Card2 is actually Card1.
