c#中关于picturebox和imagelist组件应用的问题

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

namespace picturebox
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
imageList1.ColorDepth = ColorDepth.Depth32Bit;
}

private void button1_Click(object sender, EventArgs e)
{
imageList1.Images.Clear();
string path = "1.jpg";
Image img = Image.FromFile(path,true);
imageList1.Images.Add(img);
imageList1.ImageSize=new Size(215,135);
pictureBox1.Image=imageList1.Images[1];
}

private void button2_Click(object sender, EventArgs e)
{
imageList1.Images.Clear();
string Path = "2.jpg";
Image img = Image.FromFile(Path, true);
imageList1.Images.Add(img);
imageList1.ImageSize = new Size(215,135);
pictureBox1.Image = imageList1.Images[1];
}

private void button3_Click(object sender, EventArgs e)
{
imageList1.Images.RemoveAt(0);
pictureBox1.Image = null;
}
}
}
这是书上的一个关于picture控件应用的小程序编译不报错但是运行后点BUTTON后无响应，图片有放在DEbug中
无响应就是程序卡死那种！CPU一直在50%

imageList1.Images.Clear();
string path = "1.jpg";
Image img = Image.FromFile(path,true);
imageList1.Images.Add(img);
imageList1.ImageSize=new Size(215,135);
pictureBox1.Image=imageList1.Images[0]; //注意这里的索引
}

private void button2_Click(object sender, EventArgs e)
{
imageList1.Images.Clear();
string Path = "2.jpg";
Image img = Image.FromFile(Path, true);
imageList1.Images.Add(img);
imageList1.ImageSize = new Size(215,135);
pictureBox1.Image = imageList1.Images[0];//注意这里的索引
}
