C# 实现文子从上到下，从右到左
对OnPaint()方法的重写：
 
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace OverrideOnPaint{    public partial class Form1 : Form    {        protected override void OnPaint(PaintEventArgs e)        {            base.OnPaint(e);            Rectangle r = new Rectangle(new Point(40, 40), new Size(70, 70));            StringFormat f = new StringFormat(StringFormatFlags.DirectionRightToLeft | StringFormatFlags.DirectionVertical);            e.Graphics.DrawRectangle(Pens.Green, r);            e.Graphics.DrawString("祝大家国庆节快乐!", Font, Brushes.Blue, (RectangleF)r, f);        }               public Form1()        {            InitializeComponent();        }    }}
