C# 图像控件显示绘制的几何图形

代码说明：

C# 使用图像控件显示绘制的多个几何图形，可一次显示多个绘制的图形，相关代码如下： 　　GeometryGroup MyGeometry = new GeometryGroup(); 　　MyGeometry.Children.Add(new EllipseGeometry(new Point(50, 50), 45, 20)); 　　MyGeometry.Children.Add(new EllipseGeometry(new Point(50, 50), 20, 45)); 　　RectangleGeometry MyRectangle = new RectangleGeometry(); 　　MyRectangle.Rect = new Rect(2, 2, 96, 96); 　　MyGeometry.Children.Add(MyRectangle); 　　GeometryDrawing MyDrawing = new GeometryDrawing(); 　　MyDrawing.Geometry = MyGeometry; 　　MyDrawing.Pen = new Pen(Brushes.Blue, 3); 　　DrawingImage MyImage = new DrawingImage(); 　　MyImage.Drawing = MyDrawing; 　　MyImage.Freeze(); 　　this.image1.Source = MyImage;
