WPF C#如何在代码中创建THIS绑定？

Question

我想知道,如何创建这个绑定,因为Line.X2不是依赖属性!:(

<Line Y1="0" X1="0" Y2="0" Stroke="Blue" StrokeThickness="3" Margin="0 -2 0 -2" X2="{Binding Path=RenderSize.Width, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type StackPanel}}}"/>

Line.X2 是一个依赖属性,因此您可以以正常方式执行此操作:

myLine.SetBinding(Line.X2Property,
  new Binding("RenderSize.Width")
  {
    RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(StackPanel), 1)
  });
