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[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
        }
