内存卡游戏wpf问题

我有一个记忆卡游戏，我的绑定是

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

其中初始化如下：

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 检查是否有两张卡的 IsCheck/ed 属性值 = true 并检查颜色是否相等，使 IsCheck/ed 属性中的此切换按钮为 null 但之前的算法不起作用！

这是我试图通过根据游戏而改变的结束切换按钮来实现的示例EDIT当上面的所有逻辑都正常工作时，我该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**

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以验证为什么与他关联的切换按钮也没有更改他的颜色？

2. 如何触发切换按钮始终为一种颜色？当一张卡片获得新颜色时，白色我希望他将其颜色更改为白色我怎样才能实现它？

   非常感谢。

EDIT2

我唯一的问题是绑定到颜色并更改颜色，如下所示：

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

没有让用户界面注意到它，即使卡属性发生变化并调用

  OnPropertyChanged("ButtonColor");

用户界面不会改变它

EDIT3

现在我想要一个触发器，我打开它会给任何具有白色的切换按钮白色

       <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>

当您设置您的ButtonColor, call PropertyChanged. So:

#region colorofbutton

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

    }
    #endregion
