如何在C#的图片框中使用padding移动图片？

using System;
using System.Drawing;
using System.Windows.Forms;

namespace ImagePaddingExample
{
    public partial class Form1 : Form
    {
        private PictureBox pictureBox;
        private Padding padding;

        public Form1()
        {
            InitializeComponent();

            // 创建PictureBox控件
            pictureBox = new PictureBox();
            pictureBox.SizeMode = PictureBoxSizeMode.AutoSize;
            pictureBox.Paint += PictureBox_Paint;

            // 加载图片
            pictureBox.Image = Image.FromFile("path_to_your_image");

            // 创建Padding对象
            padding = new Padding();
            padding.Left = 10;
            padding.Top = 20;

            // 将PictureBox添加到窗体上
            Controls.Add(pictureBox);
        }

        private void PictureBox_Paint(object sender, PaintEventArgs e)
        {
            // 绘制图片并应用padding
            e.Graphics.DrawImage(pictureBox.Image, padding.Left, padding.Top);
        }
    }
}
