【C#】Winform实现轮播图

复制后，需要修改的代码：

1、图片文件夹路劲：string folderPath = "C:\\Users\\Administrator\\Desktop\\images";

2、项目命名空间：namespace BuildAction

全窗口代码：

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;
using System.IO;
using System.Threading;namespace BuildAction
{public partial class Form1 : Form{private string[] imageFiles;       // 存储图片文件路径private int currentIndex = 0;      // 当前显示的图片索引private Thread rotateThread;       // 轮播线程public Form1(){InitializeComponent();}private void StartRotate(){// 读取指定文件夹下的所有图片string folderPath = "C:\\Users\\Administrator\\Desktop\\images";imageFiles = Directory.GetFiles(folderPath, "*.png", SearchOption.TopDirectoryOnly);rotateThread = new Thread(() =>{while (true){// 显示下一张图片currentIndex = (currentIndex + 1) % imageFiles.Length;this.Invoke(new Action(() =>{pictureBox1.Image = Image.FromFile(imageFiles[currentIndex]);}));// 等待 2 秒后切换图片Thread.Sleep(2000);}});rotateThread.IsBackground = true;rotateThread.Start();}private void StopRotate(){if (rotateThread != null && rotateThread.IsAlive){rotateThread.Abort();}}private void Form1_Load(object sender, EventArgs e){// 开始轮播StartRotate();}private void Form1_FormClosing(object sender, FormClosingEventArgs e){StopRotate();}private void button1_Click(object sender, EventArgs e){MessageBox.Show("测试多线程是否堵塞", "提醒");}}
}
