RectangleF is just a structure to store some info of a rectangle measured in float. GDI+ uses this structure to draw, fill the colorful stuff into it. We have to use the Graphics object to fill it. Here is the example code for you:

//Fill on a Bitmap
Graphics g = Graphics.FromImage(someBitmap);
g.FillRectangle(Brushes.Green, yourRectangleF);

In some Paint event handler, we can get the Graphics object via the passed-in argument e, normally of type PaintEventArgs, like this:

//Fill on a Form
private void Form1_Paint(object sender, PaintEventArgs e){
  e.Graphics.FillRectangle(Brushes.Green, yourRectangleF);
}
