C# Timer定时器

C# Timer定时器

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:
下面这个实力演示了每隔一秒,picturebox中的图片来回切换,每隔一秒,文本框中显示当前时间。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp2
{
    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();
        }
    }
}
