如何动态地将多个System.Windows.Media.Geometry合并到一个对象中？

Question

我有Xaml格式的徽标。

徽标应在自定义（不是我的）WPF控件中用作图标。

徽标包含几个System.Windows.Media.Geometry对象：

使用this解析一个一个几何对象的方法，它可以成功用作控件图标：

System.Windows.Media.Geometry icon_geometry = Geometry.Parse("M 263,99 ... Z");
Some_Control.Icon = icon_geometry;

现在，我需要组合几个Geometry对象。明显的Method Geometry.Combine(Geometry, Geometry, GeometryCombineMode, Transform, Double, ToleranceType)返回PathGeometry对象巫婆是不可接受的（事实上）。

是否可以将多个Geometry对象合并到一个Geometry对象中？
