How to specify rectangle stroke only on left and right in WPF?

Question

I want to have rectangle that and it should have stroke only on left and right side(not on upper and lower side). How can I do it ?

Answer 1

You can't - a rectangle only has a single stroke thickness. A Border, though, uses a thickness structure that can have different thickness on each side:

<Border BorderThickness="5,0,5,0" BorderBrush="Black" />
