如何在不打开文件对话框的情况下将图片加载到Flowlayoutpanel

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

namespace ImageLoadingExample
{
    public partial class MainForm : Form
    {
        private FlowLayoutPanel flowLayoutPanel;

        public MainForm()
        {
            InitializeComponent();
            InitializeFlowLayoutPanel();
        }

        private void InitializeFlowLayoutPanel()
        {
            // 创建FlowLayoutPanel并设置相关属性
            flowLayoutPanel = new FlowLayoutPanel();
            flowLayoutPanel.Dock = DockStyle.Fill;
            flowLayoutPanel.AutoScroll = true;

            // 将FlowLayoutPanel添加到主窗体中
            Controls.Add(flowLayoutPanel);
        }

        private void LoadImage(string imagePath)
        {
            try
            {
                // 使用Image类加载图片文件
                Image image = Image.FromFile(imagePath);

                // 创建PictureBox并设置相关属性
                PictureBox pictureBox = new PictureBox();
                pictureBox.Image = image;
                pictureBox.SizeMode = PictureBoxSizeMode.StretchImage;
                pictureBox.Width = 200;
                pictureBox.Height = 200;

                // 将PictureBox添加到FlowLayoutPanel中
                flowLayoutPanel.Controls.Add(pictureBox);
            }
            catch (Exception ex)
            {
                MessageBox.Show("加载图片出错：" + ex.Message);
            }
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            // 在窗体加载时调用LoadImage方法加载图片
            LoadImage("图片文件路径");
        }
    }
}
