Timer定时器定时器主要用到的就是Timer的Tick事件，另外还要设置时间间隔：

{public partial class Form6 : Form{public Form6(){InitializeComponent();}string path1 = @"E:\朱维照片\创作照\1.jpg";string path2= @"E:\朱维照片\创作照\2.jpg";bool flag = true;private void button1_Click(object sender, EventArgs e){timer1.Interval = 1000;timer1.Start();}private void timer1_Tick(object sender, EventArgs e){textBox1.Text = DateTime.Now.ToString();if (flag){pictureBox1.Image = Image.FromFile(path1);pictureBox1.SizeMode = PictureBoxSizeMode.Zoom;flag = false;}else{pictureBox1.Image = Image.FromFile(path2);pictureBox1.SizeMode = PictureBoxSizeMode.Zoom;flag = true;}}private void button2_Click(object sender, EventArgs e){timer1.Stop();}}
