## 上期续集–强化版 ##

**具体代码如下:**

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Windows.Forms;
    using System.Drawing.Drawing2D;//要应用GraphicsPath这个类,命名空间中必须有Drawing.Drawing2D,因为原命名空间中没有,所以需要自行添加此命名空间.
    
    namespace Test_PaoPao
    {
        
        public partial class Form1 : Form
        {

            int x = 5;//水平
            int y = 5;//垂直
            private void timer1_Tick(object sender, EventArgs e)
            {
        
                //分析:碰到顶部和底部x不变,y取反;碰到左右两边y不变,x取反
                //分两种情况:1、先碰到底部(left不变化，top正负不断变化)  2、先碰到右边(left正负不断变化，top不变)
                this.Left += x;
                this.Top += y;
                if (this.Top+this.Height>=Screen.PrimaryScreen.WorkingArea.Height||this.Top<=0)
                {
        
                    y = -y;
                    //Form1 form1 = new Form1();//实例化Form1
                    //form1.Show();//应用Form1全部属性
                    //form1.Location = new Point(300,100);
                    //form1.label1.Text = "久睡成瘾";
                }
                if (this.Left+this.Width>=Screen.PrimaryScreen.WorkingArea.Width||this.Left<=0)
