The following code example demonstrates how to load a bitmap from an Icon handle, using the GraphicsUnit enumeration, and the use of the Round method to draw the rectangle bounds of a bitmap.

This example is designed to be used with Windows Forms. Create a form that contains a button named Button2. Paste the code into the form and associate this method with the button's Click event.

private void Button2_Click(System.Object sender, System.EventArgs e)
{

    Bitmap bitmap1 = Bitmap.FromHicon(SystemIcons.Hand.Handle);
    Graphics formGraphics = this.CreateGraphics();
    GraphicsUnit units = GraphicsUnit.Point;

    RectangleF bmpRectangleF = bitmap1.GetBounds(ref units);
    Rectangle bmpRectangle = Rectangle.Round(bmpRectangleF);
    formGraphics.DrawRectangle(Pens.Blue, bmpRectangle);
    formGraphics.Dispose();
}

private void button2_Click(System.Object sender, System.EventArgs e)
{
    Bitmap bitmap1 = Bitmap.FromHicon(SystemIcons.get_Hand().get_Handle());
    Graphics formGraphics = this.CreateGraphics();
    GraphicsUnit units = GraphicsUnit.Point;
    RectangleF bmpRectangleF = bitmap1.GetBounds(units);
    Rectangle bmpRectangle = Rectangle.Round(bmpRectangleF);

    formGraphics.DrawRectangle(Pens.get_Blue(), bmpRectangle);
    formGraphics.Dispose();
} //button2_Click
