相对于形状的几何图形Geometry Compared to Shape

System.Windows.Shapes.ShapeGeometry具有、和Stroke其派生类缺少的其他呈现属性。 FillThe System.Windows.Shapes.Shape class has a Fill, Stroke, and other rendering properties that Geometry and its derived classes lack. 类是, 因此参与布局系统; 其派生类可用作支持UIElement子级的任何元素的内容。 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 , 类只定义形状的几何图形, 而不能呈现自身。The Geometry class, on the other hand, simply defines the geometry of a shape, and cannot render itself. 由于其简易性, 其使用范围更广。Because of its simplicity, it has a wider range of uses.

冻结功能: 由于Freezable Geometry该类继承自类, 因此该类提供若干特殊功能: Geometry对象可以声明为资源、在多个对象之间共享、变为只读以提高性能、克隆和使线程安全。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. 有关Freezable对象提供的不同功能的详细信息, 请参阅可冻结对象概述For more information about the different features provided by Freezable objects, see Freezable Objects Overview.
