How to add round stroke in C# win forms?

Question

C++ / C#

I make the button round with this code:

GraphicsPath myPath = new GraphicsPath();
myPath.AddEllipse(0, 0, button12.Width, button12.Height);

Region myRegion = new Region(myPath);
button12.Region = myRegion;

But when I add a stroke to the button, it makes sense that the stroke is square, and because of this, the round button gets strange lines instead of a stroke. How can I add a round stroke? Preferably without 2 elements that will be in the background of the button

Answer 1

Regions - no matter how.
The region clips the final display of the button.
Round buttons don't do that.
