C# Winform中如何绘制动画示例详解

使用如下方法调用：

using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using System.Data;  
using System.Drawing;  
using System.Drawing.Imaging;  
using System.Text;  
using System.Windows.Forms;  
 
namespace GifTest  
{  
  public partial class Form1 : Form  
  {  
    AnimateImage image;  
 
    public Form1()  
    {  
      InitializeComponent();  
      image = new AnimateImage(Image.FromFile(@"C:Documents and SettingsAdministratorMy DocumentsMy Pictures未命名.gif"));  
      image.OnFrameChanged += new EventHandler<EventArgs>(image_OnFrameChanged);  
      SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true);  
    }  
 
    void image_OnFrameChanged(object sender, EventArgs e)  
    {  
      Invalidate();  
    }  
 
    private void Form1_Load(object sender, EventArgs e)  
    {  
      image.Play();  
    }  
 
    private void Form1_Paint(object sender, PaintEventArgs e)  
    {  
      lock (image.Image)  
      {  
        e.Graphics.DrawImage(image.Image, new Point(0, 0));  
      }  
    }  
 
    private void button1_Click(object sender, EventArgs e)  
    {  
      if (button1.Text.Equals("Stop"))  
      {  
        image.Stop();  
        button1.Text = "Play";  
      }  
      else 
      {  
        image.Play();  
        button1.Text = "Stop";  
      }  
      Invalidate();  
    }  
 
    private void button2_Click(object sender, EventArgs e)  
    {  
      image.Reset();  
      button1.Text = "Play";  
      Invalidate();  
    }  
  }  
}
