c# 内存游戏，需要在游戏结束时添加消息

Question

我使用 Windows 窗体 (c#) 创建了一个内存游戏，游戏已经完成，但我很难添加最后一部分，当所有卡片都匹配时，需要向用户显示一个消息框，例如“干得好!所有卡片都已配对”。

这是一段代码，我认为将插入 MessageBox.Show 的代码:

      private void card1_Click(object sender, EventArgs e)
         //if the first slot of pendingImages is available put this card there for comparison
    {
        //turn card over
        card1.Image = Properties.Resources.Image1;
       //if this is the first card to be turned over, save its image 
        if (pendingImage1 == null)
        {
            pendingImage1 = card1;
        }
        //else check if pendingImage 2 is available then store the card here for comparison
        else if(pendingImage1 != null && pendingImage2 == null)
        {
            pendingImage2 = card1;
        }
        //if both pendingImage slots are filled then compare the cards
        if (pendingImage1 != null && pendingImage2 != null)
        {
            if (pendingImage1.Tag == pendingImage2.Tag)
            {
                //clear the variables to be used again
                pendingImage1 = null;
                pendingImage2 = null;
                //once the cards are matched and turned permanentaly, disable the card to make it unclickable
                card1.Enabled = false;
                dupCard1.Enabled = false;
                //add 10 points to the score evry time cards match
                scoreSheet.Text = Convert.ToString(Convert.ToInt32(scoreSheet.Text) + 10);
            }
            else
            {
                flipDuration.Start();
            }
        }
    }

    private void dupCard1_Click(object sender, EventArgs e)
    {
        dupCard1.Image = Properties.Resources.Image1;
        if (pendingImage1 == null)
        {
            pendingImage1 = dupCard1;
        }
        else if (pendingImage1 != null && pendingImage2 == null)
        {
            pendingImage2 = dupCard1;
        }
        if (pendingImage1 != null && pendingImage2 != null)
        {
            if (pendingImage1.Tag == pendingImage2.Tag)
            {
                pendingImage1 = null;
                pendingImage2 = null;
                card1.Enabled = false;
                dupCard1.Enabled = false;
                scoreSheet.Text = Convert.ToString(Convert.ToInt32(scoreSheet.Text) + 10);
            }
            else
            {
                flipDuration.Start();
            }
        }
    }

这 2 张是总共 18 张卡片中的第 2 张，但这是仅适用于所有卡片的代码 Properties.Resources.Image1 从 Image.1 更改为 Image.2、.3、.4 等。

我不确定什么代码可以让我在所有 9 张(总共 18 张牌)对牌都匹配后让游戏显示一个消息框。

任何帮助将不胜感激。

不确定这是否是处理此问题的“最佳”方式，但您可以跟踪已匹配的卡牌总数以及获胜所需的匹配次数。创建一个名为“winCount”的全局变量和另一个名为“currentMatches”的变量。 winCount 可以在代码中手动设置为 9 int winCount = 9，当 currentMatches == winCount 时，游戏会弹出“You Win”。

例如:

int winCount = 9;
int currentMatches = 0;

private void card1_Click(object sender, EventArgs e)
     //if the first slot of pendingImages is available put this card there for comparison
{
    //turn card over
    card1.Image = Properties.Resources.Image1;
   //if this is the first card to be turned over, save its image 
    if (pendingImage1 == null)
    {
        pendingImage1 = card1;
    }
    //else check if pendingImage 2 is available then store the card here for comparison
    else if(pendingImage1 != null && pendingImage2 == null)
    {
        pendingImage2 = card1;
    }
    //if both pendingImage slots are filled then compare the cards
    if (pendingImage1 != null && pendingImage2 != null)
    {
        if (pendingImage1.Tag == pendingImage2.Tag)
        {
            //clear the variables to be used again
            pendingImage1 = null;
            pendingImage2 = null;
            //once the cards are matched and turned permanentaly, disable the card to make it unclickable
            card1.Enabled = false;
            dupCard1.Enabled = false;
            //add 10 points to the score evry time cards match
            scoreSheet.Text = Convert.ToString(Convert.ToInt32(scoreSheet.Text) + 10);

            //NEW CODE
            currentMatches ++;
            if(currentMatches == winCount)
            {
                 MessageBox.Show("Congratulations! You Win!)
                 return;
            }
        }            
        else
        {
            flipDuration.Start();
        }     
    }
}

private void dupCard1_Click(object sender, EventArgs e)
{
    dupCard1.Image = Properties.Resources.Image1;
    if (pendingImage1 == null)
    {
        pendingImage1 = dupCard1;
    }
    else if (pendingImage1 != null && pendingImage2 == null)
    {
        pendingImage2 = dupCard1;
    }
    if (pendingImage1 != null && pendingImage2 != null)
    {
        if (pendingImage1.Tag == pendingImage2.Tag)
        {
            pendingImage1 = null;
            pendingImage2 = null;
            card1.Enabled = false;
            dupCard1.Enabled = false;
            scoreSheet.Text = Convert.ToString(Convert.ToInt32(scoreSheet.Text) + 10);
        }
        else
        {
            flipDuration.Start();
        }
    }
}
