游戏崩溃，全局:: System.Diagnostics.Debugger.Break（）;

Question

我使用UWP制作了一个meme游戏，但在我改变了某些东西之后，游戏总是在选择了两张牌后崩溃并带我到App.g.i.cs那个地方：

#if DEBUG && !DISABLE_XAML_GENERATED_BREAK_ON_UNHANDLED_EXCEPTION
        UnhandledException += (sender, e) =>
        {
            if (global::System.Diagnostics.Debugger.IsAttached)global::System.Diagnostics.Debugger.Break();
        };

ENDIF

我不知道是什么导致它，这是按钮背后的代码：

   if (IsFirstOrSecondCard && IsThirdCardChosed == false)
        {
            SecondCardChosen(sender);
        }
        else if (IsThirdCardChosed == false)
        {
            FirstCardChosen(sender);
        }
        else
            ThirdPlusButton();

这是传播给整个16个按钮的方法：

   public async void FirstCardChosen(object sender)
    {
        MemoButton[0] = (Button)sender;

        IsFirstOrSecondCard = !IsFirstOrSecondCard;

        if (MemoButton[0] == R1C1) { R1C1img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R1C1img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R1C1img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R1C2) { R1C2img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R1C2img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R1C2img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R2C3) { R2C3img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R2C3img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R2C3img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R2C4) { R2C4img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R2C4img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R2C4img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R3C1) { R3C1img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R3C1img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R3C1img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R3C2) { R3C2img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R3C2img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R3C2img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R3C3) { R3C3img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R3C3img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R3C3img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R4C1) { R4C1img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R4C1img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R4C1img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R4C2) { R4C2img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R4C2img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R4C2img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        else if (MemoButton[0] == R4C3) { R4C3img.Visibility = Visibility.Visible; await System.Threading.Tasks.Task.Delay(4000, SecondButtonTriggered.Token); R4C3img.Visibility = Visibility.Collapsed; TempImageLocation[0] = R4C3img; IsFirstOrSecondCard = !IsFirstOrSecondCard; }

        Score.Text = "Score" + Success_Counter.ToString();
    }

第二张牌：

     public async void SecondCardChosen(object sender)
    {
        IsFirstOrSecondCard = false;
        IsThirdCardChosed = true;

        Dictionary<Button, string> HiddenCardDiscovery = new Dictionary<Button, string>();

        HiddenCardDiscovery.Add(R1C1, "OriginalPepe");
        HiddenCardDiscovery.Add(R1C2, "PixelPepe");
        HiddenCardDiscovery.Add(R1C3, "IronManPepe");
        HiddenCardDiscovery.Add(R1C4, "CoolPepe");

        HiddenCardDiscovery.Add(R2C1, "UrselfPepe");
        HiddenCardDiscovery.Add(R2C2, "WinkPepe");
        HiddenCardDiscovery.Add(R2C3, "OriginalPepe");
        HiddenCardDiscovery.Add(R2C4, "HappyPepe");

        HiddenCardDiscovery.Add(R3C1, "PixelPepe");
        HiddenCardDiscovery.Add(R3C2, "MonsterPepe");
        HiddenCardDiscovery.Add(R3C3, "CoolPepe");
        HiddenCardDiscovery.Add(R3C4, "IronManPepe");

        HiddenCardDiscovery.Add(R4C1, "WinkPepe");
        HiddenCardDiscovery.Add(R4C2, "UrselfPepe");
        HiddenCardDiscovery.Add(R4C3, "MonsterPepe");
        HiddenCardDiscovery.Add(R4C4, "HappyPepe");

        MemoButton[1] = (Button)sender;


        if (MemoButton[1] == R1C1) { TempImageLocation[1] = R1C1img; }

        else if (MemoButton[1] == R1C2) { TempImageLocation[1] = R1C2img; }

        else if (MemoButton[1] == R1C3) { TempImageLocation[1] = R1C3img; }

        else if (MemoButton[1] == R1C4) { TempImageLocation[1] = R1C4img; }

        else if (MemoButton[1] == R2C1) { TempImageLocation[1] = R2C1img; }

        else if (MemoButton[1] == R2C2) { TempImageLocation[1] = R2C2img; }

        else if (MemoButton[1] == R2C3) { TempImageLocation[1] = R2C3img; }

        else if (MemoButton[1] == R2C4) { TempImageLocation[1] = R2C4img; }

        else if (MemoButton[1] == R3C1) { TempImageLocation[1] = R3C1img; }

        else if (MemoButton[1] == R3C2) { TempImageLocation[1] = R3C2img; }

        else if (MemoButton[1] == R3C3) { TempImageLocation[1] = R3C3img; }

        else if (MemoButton[1] == R3C4) { TempImageLocation[1] = R3C4img; }

        else if (MemoButton[1] == R4C1) { TempImageLocation[1] = R4C1img; }

        else if (MemoButton[1] == R4C2) { TempImageLocation[1] = R4C2img; }

        else if (MemoButton[1] == R4C3) { TempImageLocation[1] = R4C3img; }

        else if (MemoButton[1] == R4C4) { TempImageLocation[1] = R4C4img; }


        string FirstButtonImageName = "";
        string SecondButtonImageName = "";

        HiddenCardDiscovery.TryGetValue(MemoButton[0], out FirstButtonImageName);
        HiddenCardDiscovery.TryGetValue(MemoButton[1], out SecondButtonImageName);

        if (FirstButtonImageName == SecondButtonImageName)
        {
            Success_Counter += 1;
            Score.Text = "Score: " + Success_Counter.ToString();
            TempImageLocation[0].Visibility = Visibility.Visible;
            TempImageLocation[1].Visibility = Visibility.Visible;
            MemoButton[0].IsEnabled = !MemoButton[0].IsEnabled;
            MemoButton[1].IsEnabled = !MemoButton[1].IsEnabled;

            if (Success_Counter == 8)
            {
                Frame.Navigate(typeof(WonPage));
            }             
        }


        else
        {
            TempImageLocation[0].Visibility = Visibility.Visible;
            TempImageLocation[1].Visibility = Visibility.Visible;

            await System.Threading.Tasks.Task.Delay(2000);
            TempImageLocation[0].Visibility = Visibility.Collapsed;
            TempImageLocation[1].Visibility = Visibility.Collapsed;
        }
        Score.Text = "Score: " + Success_Counter.ToString();
        IsThirdCardChosed = false;
    } 

第三名：

  public void ThirdPlusButton ()
    {
        Score.Text = "Please don't press 3 buttons at the same time!"; // Add flyouut box everytime a third button gets clicked at the next update! 
    }

全局变量：

 int Success_Counter = 0;
    Button[] MemoButton = new Button[2];
    bool IsFirstOrSecondCard = false;
    bool IsThirdCardChosed = false;
    Image[] TempImageLocation = new Image[2];
    CancellationTokenSource SecondButtonTriggered = new CancellationTokenSource();

在您发表评论之前，我尝试过并帮助过： 在第二种方法（SecondCardChosen）中，在它开始之前将延迟设置为5秒：

public async void SecondCardChosen(object sender)
    {
        IsFirstOrSecondCard = false;
        IsThirdCardChosed = true;
        await System.Threading.Tasks.Task.Delay(5000);

但是，如果我没有激活一个大的延迟，游戏会崩溃并把我带到那里，尝试使用谷歌尝试寻找一个闷热，我只是没有找到任何，任何人都可以指示我正确的方向？
