如何更改WPF中TableRow的背景顏色？

Question

我創建了一個表，當MouseMove發生時，我想要更改TableRow的背景顏色， 以及MouseLeave發生時，它將返回到TableRow的舊顏色。 這裏是編碼，但它不工作。

currentRow.MouseMove += new MouseEventHandler(ShowRowColor); 
currentRow.MouseLeave += new MouseEventHandler(HideRowColor); 

void ShowRowColor(object sender, System.Windows.Input.MouseEventArgs e){ 
     TableRow tr = sender as TableRow; 
     ColorAnimation animation = new ColorAnimation(); 
     animation.From = (tr.Background as SolidColorBrush).Color; 
     animation.To = Colors.Indigo; 
     animation.Duration = new Duration(TimeSpan.FromSeconds(5)); 
     tr.BeginAnimation(SolidColorBrush.ColorProperty,animation); 
    } 

    void HideRowColor(object sender, System.Windows.Input.MouseEventArgs e) { 
     TableRow tr = sender as TableRow; 
     ColorAnimation animation; 
     animation = new ColorAnimation(); 
     animation.From = Colors.Indigo; 
     animation.To = (tr.Background as SolidColorBrush).Color; 
     animation.Duration = new Duration(TimeSpan.FromSeconds(1)); 
     tr.BeginAnimation(SolidColorBrush.ColorProperty,animation); 
    } 

請幫我...

您將要開始對TableRow的Background屬性在動畫，因爲你需要爲目標的SolidColorBrush

例的Color屬性：

tr.Background.BeginAnimation(SolidColorBrush.ColorProperty, animation);
