帮忙给下面的代码写下注释 考试要背的

在form窗体中生成随机函数
using System;
using System.Collections.Generic;

using System.Linq;
using System.Text;
using System.Windows.Forms;

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

        int n =0;
        private void button1_Click(object sender, EventArgs e)
        {
            int k = int.Parse(textBox1.Text);
            if (n < 3)
            {

                if (k == i)
                {
                    MessageBox.Show("恭喜你，猜中了！");
                    n = 0;

                }
                else
                {
                    if (k > i)
                    {
                        MessageBox.Show("大了！剩余次数："+(2-n).ToString());
                    }
                    if (k < i)
                    {
                        MessageBox.Show("小了！ 剩余次数："+(2-n).ToString());
                    }
                    n++;
                }
            }
            else
            {
                MessageBox.Show("你啊是弱智啊！！！！数字是："+i.ToString());
                
            }
        }
