跟着 伍逸 老師學GDI+

    最近在看伍逸 老師著的《C# 二維三維圖形繪製工程實例寶典》，感覺這本書太經典了，心想一定要堅持把這本書看完，爲了能勉勵自己，特註冊次博客。在此對伍逸老師表示由衷的感謝。

2.Brush的學習

  2.1 SolidBrush: 實心畫刷

  2.2 HatchBrush: 陰影畫刷

  2.3 LinerGradientBrush: 線性漸變畫刷

 用法如下：（與書上同）

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;
using System.Drawing.Drawing2D;
namespace _002Brush
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Brush brSolid = new SolidBrush(Color.Blue);
            Brush brHatch = new HatchBrush(HatchStyle.HorizontalBrick, Color.Red, Color.Yellow);
            Brush brGradient = new LinearGradientBrush(new Rectangle(0,0,200,200),Color.Black,Color.LightGray,45,false);
            g.FillRectangle(brGradient,10,10,200,200);
            g.FillEllipse(brHatch,200,200,150,190);
            g.FillPie(brSolid,0,0,300,300,285,75);
        }

    }
}

運行結果如下：
