实现效果：在Form1上添加控件PictureBox，再添加ImageList，并设置ImageList的ImageSize大小。Form1.cs代码如下：

csharpusing System;using System.Collections.Generic;using System.ComponentModel;using System.Drawing;

public partial class Form1 : Form{ public Form1() { InitializeComponent(); // 添加PictureBox控件 PictureBox pictureBox=new PictureBox(); pictureBox.Size=new Size(100, 100); // 设置控件大小 pictureBox.Location=new Point(10, 10); // 设置控件位置 this.Controls.Add(pictureBox); // 将控件添加到窗体上

// 添加ImageList控件 ImageList imageList=new ImageList(); imageList.ImageSize=new Size(32, 32); // 设置ImageList的ImageSize大小 pictureBox.ImageList=imageList; // 将ImageList赋值给PictureBox的ImageList属性 }}

实现效果：

注意：using system.io; 往Form1上添加控件picturebox，再添加imagelist，并设置imagelist的imagesize大小

Form1.cs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; namespace ImageCheck { public partial class Form1 : Form { public Form1() { InitializeComponent(); } int index; private void button1_Click(object sender, EventArgs e) { index--; if (index<0) { MessageBox.Show("去往最后一张图片"); index = imageList1.Images.Count - 1; } this.pictureBox1.Image = this.imageList1.Images[index]; } private void button2_Click(object sender, EventArgs e) { index++; if (index>imageList1.Images.Count-1) { MessageBox.Show("回到第一张图片"); index = 0; } this.pictureBox1.Image = this.imageList1.Images[index]; } private void LoadImage() { string rootPath = Application.StartupPath; string filePath = rootPath + @"\image"; DirectoryInfo rootDir = new DirectoryInfo(filePath); FileInfo[] file = rootDir.GetFiles(); for (int i=0;i<=file.Length-1;i++) { Image img = Image.FromFile(file[i].FullName); this.imageList1.Images.Add(img); } } private void Form1_Load(object sender, EventArgs e) { LoadImage(); this.pictureBox1.Image = this.imageList1.Images[index]; } } }

注意：在C#的工作目录Debug下创建image文件夹，并放置图片
