主要就是几个要点：
1、多线程
2、按钮位置改变计算（不要超出界面）
3、资源的使用（主要是只要一个exe就可以，不用多余的文件）
直接代码吧，没啥好讲的。主要是我用来哄老婆的(*￣︶￣)
public partial class Form1 : Form{private bool IsForgive = false;private int index = 0;private List<Bitmap> files = new List<Bitmap> { Resource1.pic1, Resource1.pic2 };private Random random;public Form1(){InitializeComponent();}private void Form1_Load(object sender, EventArgs e){var thread = new Thread(PicChange);thread.IsBackground = true;thread.Start();}private void PicChange(){while (!IsForgive){Image img= files[index++ % files.Count];pictureBox1.Image = img;pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;Thread.Sleep(1000);}pictureBox1.Image = Resource1.forgive;}private void button2_MouseMove(object sender, MouseEventArgs e){random = new Random(DateTime.Now.Millisecond);var r1 = random.Next(100, 200);var r2 = random.Next() % 2 == 1 ? -1 : 1;var point = button2.Location;point.X = Math.Abs(point.X + (r1) * r2) % (this.Size.Width - button2.Size.Width);point.Y = Math.Abs(point.Y + (r1) * r2) % (this.Size.Height - button2.Size.Width);button2.Location = point;}private void button1_Click(object sender, EventArgs e){button2.Hide();button1.Hide();IsForgive = true;Image image = Resource1.forgive;pictureBox1.Image = image;}}
效果界面：
