存储卡游戏WPF问题

我有一个记忆卡游戏,我的绑定是到

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

如下面所示:

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;

        }

如果(已选择.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
}

}

我努力实现记忆卡游戏的目标 检查是否有两张卡的is check/ed属性值为true,如果颜色相等,则检查其中的颜色。在is check/ed属性中,使此切换按钮为空。 但是先前的算法不起作用!!

这是一个例子,我试图通过结束一个切换按钮来实现什么,这个按钮根据游戏的不同而改变。 编辑 当上面所有的逻辑都在工作时,我如何使用触发器来完成它?…

<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,我有两个关于我的代码的问题

1. 我把卡片的颜色改成了白色,为什么连拨动按钮也不改颜色呢?

2. 我怎样才能将切换按钮调整为一种颜色?当一张牌变成新颜色时,我要他把颜色改成白色,我怎么才能做到?

   非常感谢。

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);

不要让用户界面注意到它,甚至认为卡属性发生了变化并调用

  OnPropertyChanged("ButtonColor");

用户界面不会改变它

现在我想要一个触发器,当我在它上面时,它会给任何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>
