你如何以编程方式在Silverlight中定位对象？

    <Rectangle x:Name="MyRectangle" Width="100" Height="50" Fill="Red" />
</Canvas>

MyRectangle.SetValue(Canvas.LeftProperty, 50.0);
MyRectangle.SetValue(Canvas.TopProperty, 20.0);

<Rectangle x:Name="MyRectangle" Width="100" Height="50" Fill="Red">
    <Rectangle.RenderTransform>
       <TranslateTransform x:Name="MyTranslateTransform" />
    </Rectangle.RenderTransform>
</Rectangle>

MyTranslateTransform.X = 50.0;
MyTranslateTransform.Y = 20.0;
