using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    
    namespace LoadPictureApplication
    {
        public partial class Form1 : Form
        {
            Image lightImage = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "light.png");//light.png图片
            Image normalImage = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + "normal.png");//light.png图片
            bool boo = true;
            public Form1()
            {
                InitializeComponent();
            }
    
            private void button1_Click(object sender, EventArgs e)
            {
                int i = 0;
                String pbName = "pictureBox" + (i + 1);
                
    
                 if (boo)
                {
    
                    PictureBox pb = ((PictureBox)this.Controls.Find(pbName, true)[0]);
    
                    pb.Image = lightImage;
                    boo = false;
                }
                else {
                    PictureBox pb = ((PictureBox)this.Controls.Find(pbName, true)[0]);
    
                    pb.Image = normalImage;
                    boo = true;
                }
            }
        }
