        将Form的FormBorderStyle设置为None, 运行就是没边界的窗口可移动的窗口啦

 

　　程序中多个无Border的窗口就可以直接继承这个类就可以了, 为了便于理解, 这个继承自Form的类叫FormParent, 且在上面添加一个Button, Text = "ParentForm"

　　其Click事件添加代码

1 private void button1_Click(object sender, EventArgs e)2         {3             FormSon f = new FormSon();4             f.Show();5             this.Hide();6         }

　　新建一个Windows Form, 取名叫FormSon, 让其继承于FormParent

1 public partial class FormSon : FormParent //!!!!!!!!!!!!!!!!!!!!!!!!!!!!2     { 3         public FormSon()4         {5             InitializeComponent();6         }7     }

　　运行程序点击FormParent就会弹出一模一样的FormSon出来, 说明还真是亲生的

 

　　但是人总是要有个性的, 我们修改FormSon的Button控件, 发现修改不了, 其实这不是家族遗传病, 是因为FormParent的Modifires属性设置为了Private, 改成Public就可以啦！
