[Silverlight, C#] Create a simple dashed border

It is simple to set a dashed border of any shape [in my case I was setting a Rectangle border] ... simply set the StrokeDashArray property.

StrokeDashArray = "[Length of dash],[Length of gap], ..."
You can repeat the dash/gap pairs to create different patterns on the same stroke.

XAML:
<. Rectangle ... StrokeDashArray="5.0, 2.0" ./>

C#:
Rectangle lasso = new Rectangle();
...
lasso.StrokeDashArray = new DoubleCollection { 5.0, 2.0 };
