我有一个绘图视觉,我有图纸,如何将其添加到我的画布和显示？

 DrawingVisual drawingVisual = new DrawingVisual();

 // Retrieve the DrawingContext in order to create new drawing content.
 DrawingContext drawingContext = drawingVisual.RenderOpen();

 // Create a rectangle and draw it in the DrawingContext.
 Rect rect = new Rect(new System.Windows.Point(0, 0), new System.Windows.Size(100, 100));
 drawingContext.DrawRectangle(System.Windows.Media.Brushes.Aqua, (System.Windows.Media.Pen)null, rect);

 // Persist the drawing content.
 drawingContext.Close();

如何将其添加到画布？假设我有一个Canvas

  Canvas canvas = null;
  canvas.Children.Add(drawingVisual); //Doesnt work as UIElement expected.

如何将drawingVisual添加到画布？

TIA.
