define style in code

Question

  < Canvas.Resources >
    < Style  TargetType = "{x:Type Path}" BasedOn="{StaticResource "{x:Type Path}>
         < Setter Property = "Stroke" Value = "Black" />
            < Setter Property = "StrokeThickness" Value = "0.7" />
               < Setter Property = "Canvas.Left" >
                    < Setter.Value >
                      < MultiBinding Converter = "{StaticResource multiply2Numbers}" >
                          < Binding Path = "RenderTransformOrigin.X" RelativeSource = "{RelativeSource Self}" />
                          < Binding Path = "Scale" RelativeSource = "{RelativeSource AncestorType={x:Type Canvas}}" />
                      </ MultiBinding >
                  </ Setter.Value >
              </ Setter >
              < Setter Property = "Canvas.Top" >
                  < Setter.Value >
                      < MultiBinding Converter = "{StaticResource multiply2Numbers}" >
                          < Binding Path = "RenderTransformOrigin.Y" RelativeSource = "{RelativeSource Self}" />
                          < Binding Path = "Scale" RelativeSource = "{RelativeSource AncestorType={x:Type Canvas}}" />
                      </ MultiBinding >
                  </ Setter.Value >
              </ Setter >
          </ Style >
      </ Canvas.Resources >

how to create the above resources in code?
we need this class to work as Custom Control,
Note: the code is for a base class and we want all derived classes children (of type Path) to apply this style.
Note: prop Scale is a DependenceyProperty we already defined.

Hi,
I hope my code helps you. In the past you have never rated my answers as helpful.

public class CanvasWithItemsSource : Canvas
  {
    public CanvasWithItemsSource()
    {
      Style st = new Style(typeof(Path));
      st.Setters.Add(new Setter(Path.StrokeProperty, Brushes.Black));
      st.Setters.Add(new Setter(Path.StrokeThicknessProperty, 0.7));
      IMultiValueConverter converter = new Multiply2Numbers();
      MultiBinding binding1 = new MultiBinding() { Converter = converter };
      binding1.Bindings.Add(new Binding("RenderTransformOrigin.X") { RelativeSource = RelativeSource.Self });
      binding1.Bindings.Add(new Binding("Scale") { RelativeSource = new RelativeSource() { AncestorType = typeof(Canvas) } });
      st.Setters.Add(new Setter(Canvas.LeftProperty, binding1));
      MultiBinding binding2 = new MultiBinding() { Converter = converter };
      binding2.Bindings.Add(new Binding("RenderTransformOrigin.Y") { RelativeSource = RelativeSource.Self });
      binding2.Bindings.Add(new Binding("Scale") { RelativeSource = new RelativeSource() { AncestorType = typeof(Canvas) } });
      st.Setters.Add(new Setter(Canvas.TopProperty, binding2));
      this.Resources.Add(typeof(Path), st);
    }
