HOW TO：不使用腳本而建立屬性的動畫
更新：2007 年 11 月
本範例說明如何在不使用 Storyboard 的情況下，將動畫套用到屬性的一種方式。
.gif "注意事項") 注意事項： |
|---|
可延伸標記語言 (XAML) 無法使用這個功能。如需在 XAML 中將屬性顯示為動畫的詳細資訊，請參閱 HOW TO：使用腳本建立屬性的動畫。 |
若要將本機動畫套用到屬性，請使用 BeginAnimation 方法。這個方法接受兩個參數：一是 DependencyProperty，用來指定要顯示為動畫的屬性，另一是要套用到該屬性的動畫。
範例
下列範例顯示如何將 Button 的寬度和背景色彩顯示為動畫。

System.Windows.Media.Animation 命名空間有各種動畫類別，可用來將不同型別的屬性顯示為動畫。如需將屬性顯示為動畫的詳細資訊，請參閱動畫概觀。如需相依性屬性 (這些範例中顯示之屬性的型別) 及其功能的詳細資訊，請參閱相依性屬性概觀。
另外還有其他方式可以在不使用 Storyboard 物件的情況下顯示動畫；如需詳細資訊，請參閱建立屬性動畫技術概觀。
