呵呵，终于进入到我感兴趣的窗口方面的操作啦。。

三个窗口的SHOW和HIDE。。。

PROGRAM.CS中记录第一个加载的窗口FORM

using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;using System.Windows.Forms;namespace WindowsFormsApplication1{    static class Program    {        /// 
        /// The main entry point for the application.        /// 
        [STAThread]        static void Main()        {            Application.EnableVisualStyles();            Application.SetCompatibleTextRenderingDefault(false);            Application.Run(new Form1());        }    }}

FORM1.CS的主要代码如下：

1 using System; 2 using System.Collections.Generic; 3 using System.ComponentModel; 4 using System.Data; 5 using System.Drawing; 6 using System.Linq; 7 using System.Text; 8 using System.Threading.Tasks; 9 using System.Windows.Forms;10 11 namespace WindowsFormsApplication112 {13     public partial class Form1 : Form14     {15         public Form1()16         {17             InitializeComponent();18         }19 20         private void label1_Click(object sender, EventArgs e)21         {22 23         }24 25         private void button1_Click(object sender, EventArgs e)26         {27             Form2 frm2 = new Form2();28             frm2.Show();29         }30 31         private void button2_Click(object sender, EventArgs e)32         {33             Form3 frm3 = new Form3();34             frm3.Show();35         }36 37         private void Form1_Load(object sender, EventArgs e)38         {39         }40     }41 }

至于下面这个代友乾坤，以后要慢慢研究的。

好像不建议手工更改，都是通过界面设置属性的。
