Help needed with a complicated application

[Lucy]

Is there a way of calling a method but not calling the first line of the method? I have a generic List called PlayHand. I add to this list in the method PlayGame(). When the button is clicked I want to add a Card type to this list. But after the method PlayGame() has been called and the method has completed, the generic list PlayHand clears. Can anyone help? Im really stuck on this! Lucy

I don't think so. What you can do is add boolean parameter to that method, and have condition on first line, something like

void MyMethod(bool shouldExecuteFirstLine)
{
  if(shouldExecuteFirstLine)
  {
   ...
  }
   /* rest of method body */
}

Uh, I don't follow :( Can you show your code?

Sounds like your problem is tha the list is created inside the method and so has no state. Is it a member ? If it is, then it's Clear method is being called somewhere. What is this first line you're trying to avoid ( it can't be done without the approach someone else offered ) ?

Sorry I am very new to C# and I am trying alter a console application example from a book to a windows form to test my skills and how much I have learnt. I think I haven't learnt to much and I have taken on a huge task. I have this method PlayGame() public void PlayGame() { Player[] players = new Player[1]; for (int p = 0; p < players.Length; p++) { string playerName = listBox1.SelectedItem.ToString(); players[p] = new Player(playerName); } if (players == null) return; for (int p = 0; p < players.Length; p++) { for (int c = 0; c < 7; c++) { players[p].PlayHand.Add(playDeck.GetCard(currentCard++)); } } //int currentPlayer; Card playCard = playDeck.GetCard(currentCard++); discardedCards.Add(playCard); for (currentPlayer = 0; currentPlayer < players.Length; currentPlayer++) { label1.Text = players[currentPlayer].Name + "'s turn."; labelHiden.Text = Convert.ToString(currentPlayer); label2hiden.Text = Convert.ToString(players[currentPlayer]); foreach (Card card in players[currentPlayer].PlayHand) { listBox2.Items.Add(Convert.ToString(card)); //richTextBox1.Text = Convert.ToString(card); } label3.Text = "Card in play: " + playCard; if (discardedCards.Contains(playCard)) { discardedCards.Remove(playCard); } players[currentPlayer].PlayHand.Add(playCard); label1.Text = "Drawn: " + playCard; label1.Text = "New Hand:"; for (int i = 0; i < players[currentPlayer].PlayHand.Count; i++) { listBox2.Items.Add(i + 1 + ": " + players[currentPlayer].PlayHand[i]); //richTextBox1.Text = i + 1 + ": " + players[currentPlayer].PlayHand[i]; } label3.Text = "Choose card to discard:"; } current = playCard; //return; } I only want this section of code to execute if a button is clicked: if (discardedCards.Contains(playCard))

As I thought, this creates a new local variable. Turn it into a member if you want to reuse it.

Thank you! I will try that now. Lucy
