Paths and Geometries
So far, you've looked at a number of classes that derive from Shape, including Rectangle, Ellipse, Line, Polygon, and Polyline. However, there's one Shape-derived class that you haven't considered yet, and it's the most powerful by far. The Path class has the ability to encompass any simple shape, groups of shapes, and more complex ingredients such as curves.
The Path class includes a single property, Data, that accepts a Geometry object that defines the shape (or shapes) the path includes. You can't create a Geometry object directly because it's a MustInherit class. Instead, you need to use one of the derived classes listed in Table 8-3. All of these classes are found in the System.Windows.Media namespace.
