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！
