如何在运行时使用C#中的计算机鼠标单击将图片添加到窗体？

using System;
using System.Windows.Forms;

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

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Filter = "Image Files|*.jpg;*.jpeg;*.png;*.gif";
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                string selectedImage = openFileDialog.FileName;
                pictureBox1.Image = Image.FromFile(selectedImage);
                pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
                pictureBox1.Size = new System.Drawing.Size(300, 200);
                pictureBox1.Location = new System.Drawing.Point(50, 50);
            }
        }
    }
}
