Drawing getbounds rectangle or rectangleF?

I have a List with float coordinates and I'm trying to draw a rectangle around a line previously drawn.

Graphics G = e.Graphics;    
Pen pen5 = new Pen(Color.DodgerBlue, 0.01f);
var rect2 =  new RectangleF();

GraphicsPath maliOkvir = new GraphicsPath();
maliOkvir.AddLine(((float)(odabraniSegment[0].startX)),
                   (float)(odabraniSegment[0].startY),
                   (float)(odabraniSegment[0].endX),
                   (float)(odabraniSegment[0].endY));

rect2 = maliOkvir.GetBounds();
G.DrawRectangle(pen5, rect2);

I'm getting an error on rect2 part:

G.DrawRectangles(pen5, rect2);

Cannot convert from 'System.Drawing.RectangleF' to 'System.Drawing.RectangleF[]'

How can I fix this? tried multiple variations of Rectangle and RectangleF, none works together.. the end result should look like this:

You're using the DrawRectangles() method of System.Drawing.Graphics, which expects an array of Rectangles.

Use the singular version: DrawRectangle():

G.DrawRectangle(pen5, rect2.Left, rect2.Top, rect2.Width, rect2.Height); // Singular

MSDN gives you (a lot) of information about the Graphics class.

Hope this helps!

The DrawRectangles method expects an array of Rectangle or RectangleF objects but you are only passing in a single item. You should either:

  1. Switch to use the singular version of the method, i.e. DrawRectangle

  2. Pass in an array:

    G.DrawRectangles(pen5, new [] { rect2 });
