private void button2_Click(object sender, EventArgs e)
        {
            int j = 0;
            for (j = 0; j < imageList1.Images.Count; j++)
            {
                if (pictureBox1.Image == imageList1.Images[j] && imageList1.Images.Count > j + 1)
                {
                    pictureBox1.Image = imageList1.Images[j + 1];
                    return;
                }
            }            if (j == imageList1.Images.Count)
            {
                MessageBox.Show("与" + hz + "相关的图片已浏览完!");
                imageList1.Dispose();
            }
