Question

: Let’s say we are working with shapes having different types like 2d, 3D and so on. Using private access to fields of class design a class for rectangle.    

c# for both 2d and 3d rectangle

Answer 1

private void Draw2d3d(Graphics gr, Rectangle rect,

rectStyle rect_style, bool sunken)

{

if (rect_style == RectStyle.FixedSingle)

{

rect.Width -= 1;

rect.Height -= 1;

gr.DrawRectangle(Pens.Black, rect);

}

else if (rect_style == RectStyle.Fixed3D)

{

Color[] colors;

if (sunken)

{

colors = new Color[]

{

SystemColors.ControlDark,

SystemColors.ControlDarkDark,

SystemColors.ControlLightLight,

SystemColors.ControlLight

};

}

else

{

colors = new Color[]

{

SystemColors.ControlLightLight,

SystemColors.ControlLight,

SystemColors.ControlDark,

SystemColors.ControlDarkDark

};

}

using (Pen p = new Pen(colors[0]))

{

gr.DrawLine(p, rect.X, rect.Bottom - 1,

rect.X, rect.Y);

gr.DrawLine(p, rect.X, rect.Y,

rect.Right - 1, rect.Y);

}

using (Pen p = new Pen(colors[1]))

{

gr.DrawLine(p, rect.X + 1, rect.Bottom - 2,

rect.X + 1, rect.Y + 1);

gr.DrawLine(p, rect.X + 1, rect.Y + 1,

rect.Right - 2, rect.Y + 1);

}

using (Pen p = new Pen(colors[2]))

{

gr.DrawLine(p, rect.X, rect.Bottom - 1,

rect.Right - 1, rect.Bottom - 1);

gr.DrawLine(p, rect.Right - 1, rect.Bottom - 1,

rect.Right - 1, rect.Y);

}

using (Pen p = new Pen(colors[3]))

{

gr.DrawLine(p, rect.X + 1, rect.Bottom - 2,

rect.Right - 2, rect.Bottom - 2);

gr.DrawLine(p, rect.Right - 2, rect.Bottom - 2,

rect.Right - 2, rect.Y + 1);

}

}
