RectangleF

RectangleF serializable

System.Drawing (system.drawing.dll) struct

This value type is the real equivalent of the integer-based Rectangle . Again, it defines a rectangular region of a 2D surface. It offers all the basic facilities of the Rectangle structure, and a conversion operator to convert from a Rectangle .

As with the Point / PointF pair, there is no intrinsic performance advantage in using the integer Rectangle , as all the Graphics painting methods are implemented in terms of the real version anyway (in the first release of the framework).

The same rendering issues also apply as for Rectangle -based shapes if you are not aligned to the pixel boundaries of the target device.
