									using System.ComponentModel;

									using System.Data;

									using System.Drawing;

									using System.Linq;

									using System.Text;

									using System.Threading.Tasks;

									using System.Windows.Forms;

									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];
