【BringToFront()和SendToBack()】

Question

c#中如何让多个panel在一个form窗体中显示？
如果这些panel是叠在一起的，也就是location和size的值是一样的时候，
可以用panel.BringToFront()和panel1.SendToBack()控制怎样设置呢？谢谢

Answer 1

点击不同button时，显示不同panel

Answer 2

要显示某panel 就那panel 的对象.BringToFront()；
其他就不用SendToBack

Answer 3

我觉得调用BringToFront()就可以了，需要谁就把谁提前，调用SendToBack()意义不大，因为推后之后要显示哪个panel并不确定

Panel p1 = new Panel();
        Panel p2 = new Panel();
        Panel p3 = new Panel();
        private void Form3_Load(object sender, EventArgs e)
        {
            SplitContainer splitContainer1 = new SplitContainer();
            splitContainer1.Dock = System.Windows.Forms.DockStyle.Fill;
            splitContainer1.Location = new System.Drawing.Point(0, 0);
            splitContainer1.Name = "splitContainer1";            p1.BackColor = Color.Red;
            p1.Dock = DockStyle.Fill;
            splitContainer1.Panel2.Controls.Add(p1);
            p2.BackColor = Color.Black;
            p2.Dock = DockStyle.Fill;
            splitContainer1.Panel2.Controls.Add(p2);
            p3.Dock = DockStyle.Fill;
            p3.BackColor = Color.Blue;
            splitContainer1.Panel2.Controls.Add(p3);            Button b1 = new Button();
            b1.Text = "p1";
            b1.Click += new EventHandler(button1_Click);
            b1.Location = new Point(0, 20);
            splitContainer1.Panel1.Controls.Add(b1);            Button b2 = new Button();
            b2.Text = "p2";
            b2.Click += new EventHandler(button2_Click);
            b2.Location = new Point(0, 50);
            splitContainer1.Panel1.Controls.Add(b2);            Button b3 = new Button();
            b3.Text = "p3";
            b3.Click += new EventHandler(button3_Click);
            b3.Location = new Point(0, 80);
            splitContainer1.Panel1.Controls.Add(b3);            splitContainer1.Dock = DockStyle.Fill;
            this.Controls.Add(splitContainer1);
        }        private void button1_Click(object sender, EventArgs e)
        {
            p1.BringToFront();
        }        private void button2_Click(object sender, EventArgs e)
        {
            p2.BringToFront();
        }        private void button3_Click(object sender, EventArgs e)
        {
            p3.BringToFront();
        }

注册Form3_Load事件然后拷贝代码后直接运行
