備註

相對於圖形的幾何Geometry Compared to Shape

System.Windows.Shapes.Shape類別Geometry具有、和Stroke其他呈現屬性, 而其衍生類別卻缺乏。 FillThe System.Windows.Shapes.Shape class has a Fill, Stroke, and other rendering properties that Geometry and its derived classes lack. 類別是, 因此會參與配置系統; 它的衍生類別可以當做支援UIElement子系之任何專案的內容使用。 FrameworkElement ShapeThe Shape class is a FrameworkElement and therefore participates in the layout system; its derived classes can be used as the content of any element that supports UIElement children.

另一方面Geometry , 類別只會定義圖形的幾何, 而無法呈現本身。The Geometry class, on the other hand, simply defines the geometry of a shape, and cannot render itself. 因為其簡單性, 所以有更廣泛的使用範圍。Because of its simplicity, it has a wider range of uses.

無法凍結的功能: 因為它繼承Freezable自類別Geometry , 所以類別提供數個特殊功能: Geometry物件可以宣告為資源, 在多個物件之間共用, 使其成為唯讀以改善效能、複製和設為安全線程。Freezable Features: Because it inherits from the Freezable class, the Geometry class provides several special features: Geometry objects can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. 如需Freezable物件所提供之不同功能的詳細資訊, 請參閱可凍結物件總覽For more information about the different features provided by Freezable objects, see Freezable Objects Overview.

給繼承者的注意事項

雖然此類別是抽象的, 但它不是可公開擴充的。Although this class is abstract, it is not publicly extensible.
