winform 利用image实现变脸小动画

public partial class Frm_Main : Form { string strPath; public Frm_Main() { InitializeComponent(); } private void Frm_Main_Load(object sender, EventArgs e) { strPath = Application.StartupPath.Substring(0, Application.StartupPath.Substring(0, Application.StartupPath.LastIndexOf("\\")).LastIndexOf("\\"));//截取图片所在的文件路径 pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage; //设置图片的显示类型 pictureBox1.Image = Image.FromFile(strPath @"\image\1.jpg");//为pictureBox1设置显示的图片 } private void timer1_Tick(object sender, EventArgs e) { Random r = new Random(); //声明一个随机类的对象 pictureBox1.Image = Image.FromFile(strPath @"\image\" r.Next(1, 5) ".jpg");//为pictureBox1设置显示的图片 }
