内存卡游戏wpf问题

Question

我有一个记忆卡游戏，我的绑定是

public ObservableCollection<List<memoryCard>> MyCollection { get; set; }//holding the array 

在哪里初始化是这样的：

for (int i = 0; i < Size; i++)
        {
            List<memoryCard> list = new List<memoryCard>();

            for (int j = 0; j < Size; j++)
            {
                var card = new memoryCard(createRandomBrush(array, j));
                card.IsChecked = false;
                list.Add(card);
                card.PropertyChanged += (a, b) => Verify(b.PropertyName);
            }
            MyCollection.Add(list);
        }
**EDIT its now working except to the one EDIT in the middle who do me an hard time **
     private void Verify(string propName)
    {
        if (propName != "IsChecked2")
        {
            return;
        }

       // List<memoryCard> selected = new List<memoryCard>();
        foreach (List<memoryCard> observerListItem in MyCollection)
            foreach (memoryCard mycard in observerListItem)
                if (mycard.IsChecked == true)
                    selected.Add(mycard);

        if (selected.Count == 2)
        {
            if ((selected.First().buttonColor == selected.Last().buttonColor) && 
                (!selected.First().Equals(selected.Last()  )   )   )
            {
                if (firstClick)
                {
                    MessageBox.Show("Good.", "Result", MessageBoxButton.OK, MessageBoxImage.Information);
                    firstClick = !firstClick;
 selected.ForEach(cell => cell.buttonColor = Brushes.White);
                    //here the biding color of the toggle item should chang and it doesnt can someone explain me how to do it right ?ite
                }

                }
            }
            else
            {
                if (firstClick)
                {
                    MessageBox.Show("Bad.", "Result", MessageBoxButton.OK, MessageBoxImage.Error);
                    firstClick = !firstClick;
                }
            }
            selected.First().IsChecked = selected.Last().IsChecked = false;
            selected.Clear();
            firstClick = true;
         
        }

if (selected.Count!=0)selected.First().IsChecked = false; }

and my memoreycard class is :


 public class memoryCard : INotifyPropertyChanged
{
    #region c'tor
    public memoryCard(Brush _buttonColor)
    {
        buttonColor=_buttonColor;
    }
    #endregion
    private bool ?_isChecked = false;
    public bool ?IsChecked
    {
        get
        {
            return _isChecked;
        }
        set
        { 
            if (_isChecked != value)
            {
                _isChecked = value;
                //OnPropertyChanged("IsChecked");
                OnPropertyChanged("IsChecked2");
            }
        }
    }

    #region colorofbutton
        
        public Brush buttonColor;
        public Brush ButtonColor
        {
            get
            {
                return buttonColor;
            }
            set
            {
                buttonColor = value;
            }
            
        }
        #endregion

    
    
    #region INotifyPropertyChanged Members

        public event PropertyChangedEventHandler PropertyChanged;

        private void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
        #endregion
}

}

我尝试实现记忆卡游戏的目标 检查是否有两张卡是 IsCheck/ed 属性 value = true 并检查颜色是否颜色相等 使 IsCheck/ed 属性中的此切换按钮为 null 但是之前的算法不起作用！！

这是我试图通过根据游戏更改的结束切换按钮来实现的示例 编辑 当上述所有逻辑都正常工作时，我如何使用触发器来做到这一点？...

<ControlTemplate x:Key="ButtonControlTemplate1" TargetType="{x:Type ToggleButton}">
            <Grid>
                <Ellipse Name="elipse1" Height="65" Width="79" Fill="{Binding Path=ButtonColor}" Visibility="Collapsed"></Ellipse>
                <Ellipse Name="elipse2" Height="65" Width="79" Fill="Black" ></Ellipse>
            </Grid>
            <ControlTemplate.Triggers>
                <Trigger Property="IsPressed" Value="True">
                    <Setter TargetName="elipse1" Property="Visibility" Value="Visible"/>
                    <Setter TargetName="elipse2" Property="Visibility" Value="Collapsed"/>
                </Trigger>

                <Trigger Property="IsCheck" Value="null">
                    <Setter TargetName="elipse1" Property="Visibility" Value="Collapsed"/>
                    <Setter TargetName="elipse2" Property="Visibility" Value="Collapsed"/>
                </Trigger>

                
            </ControlTemplate.Triggers>
        </ControlTemplate>

** 编辑**

所以总结一下，我对我的代码有两个问题

1. 我将卡片颜色更改为白色，为什么与他关联的切换按钮也没有改变他的颜色？

2. 我怎样才能使切换按钮始终为一种颜色？当一张卡片获得新颜色时，我希望他改变颜色以使其成为白色，我该如何实现它？

   非常感谢。

EDIT2

我唯一的问题是绑定到颜色并像这样更改颜色：

     selected.ForEach(cell => cell.buttonColor = Brushes.White);

没有让用户界面注意到它，即使卡片属性发生了变化并调用

  OnPropertyChanged("ButtonColor");

用户界面不会改变它

EDIT3

现在我想要一个触发器，当我打开它时，它会给任何白色的切换按钮提供白色

       <ControlTemplate x:Key="ButtonControlTemplate1" TargetType="{x:Type ToggleButton}">
            <Grid>
                <Ellipse Name="elipse1" Height="65" Width="79" Fill="{Binding Path=ButtonColor}" Visibility="Collapsed"></Ellipse>
                     <Ellipse Name="elipse2" Height="65" Width="79" Fill="Black" ></Ellipse>
     <Ellipse Name="elipse3" Height="65" Width="79" Fill="Black" Visibility="Collapsed" ></Ellipse>
            </Grid>
            <ControlTemplate.Triggers>
                <Trigger Property="IsPressed" Value="True">
                    <Setter TargetName="elipse1" Property="Visibility" Value="Visible"/>
                    <Setter TargetName="elipse2" Property="Visibility" Value="Collapsed"/>
                </Trigger>

                <Trigger Property="IsCheck" Value="null">
                    <Setter TargetName="elipse1" Property="Visibility" Value="Collapsed"/>
                    <Setter TargetName="elipse2" Property="Visibility" Value="Collapsed"/>
        <Setter TargetName="elipse3" Property="Visibility" Value="Visible"/>

                </Trigger>

Answer 1

当您设置ButtonColor 时，请致电PropertyChanged。所以：

#region colorofbutton

    private Brush buttonColor; // Use the property accessors instead
    public Brush ButtonColor
    {
        get
        {
            return buttonColor;
        }
        set
        {
            buttonColor = value;
            OnPropertyChanged("ButtonColor");
        }

    }
    #endregion
