在 WPF 中选择绘图和形状
我不太确定 System.Windows.Media.Drawing 类和 System.Windows.Shapes.Shape 类之间的区别。它们都公开了与 WPF 中 2D 图形相关的功能。您什么时候会在 WPF 应用程序中选择一个，什么时候会选择另一个？
I am not quite sure about the differences between the classes System.Windows.Media.Drawing and System.Windows.Shapes.Shape. They both expose functionality related to 2D graphics in WPF. When would you choose one in your WPF application, and when would you choose the other?

Shape继承自 FrameworkElement 因此是一个高级对象，提供命中测试、样式、布局和数据绑定等功能。相比之下， 绘图 不会继承自 < code>FrameworkElemet 并且不支持任何这些功能。正如文档提到的，Drawing对于轻量级视觉对象很有用。如果您正在创建一个复杂的画笔来绘制区域或背景，那么 DrawingBrush 将非常有效。绘图可以组合文本、视频、图像和几何 对象（另一个轻量级类）来创建复杂但非常高效且快速的绘图。
简而言之，
Drawing是Shape的低级替代方案。至于用例，这取决于。
OnRender来绘制东西，您主要会使用几何图形。Drawing也是Freezable，因此可以在线程之间共享（假设它被冻结）。A
Shapeinherits from FrameworkElement and is therefore a high level object which provides features such as hit-testing, styling, layout and data binding. In contrast a Drawing does not inherit fromFrameworkElemetand doesn't support any of these features. As the documentation mentions aDrawingis useful for lightweight visual objects. If you are creating a complex brush to use to paint areas or a background a DrawingBrush would be very efficient.Drawings can combine text, video, images and Geometry objects (another light weight class) to create complex but very efficient and fast drawings.
In short a
Drawingis a low-level alternative to aShape.As for use cases, it depends.
OnRenderyou would mostly use Geometries.A
Drawingis alsoFreezableand can thus be shared among threads (assuming it is frozen).
