How can I intersect two (.NET) GraphicsPath objects?
Are you trying to get the area enclosed by two different paths? That is a Region, not a path:
var rgn1 = new Region(path1);
var intersection = rgn1.Intersect(path2);
rgn1.Dispose();
If that is not what you mean, you will have to provide more information.
