Is it important to dispose SolidBrush and Pen?

Question

I recently came across this VerticalLabel control on CodeProject.

I notice that the OnPaint method creates but doesn\'t dispose Pen and SolidBrush objects.

Answer 1

The objects should be disposed of by the garbage collection after they've fallen out of scope as long as they're not referenced by anything else.

The simplest way to demonstrate whether this is happening or not (without making any code changes) is to use a large number of these controls on a form and see if the memory used by the application keeps growing or remains stable.
