listview的用法？

private void button1_Click(object sender, EventArgs e) { this.button1.Dock = DockStyle.Top; this.button3.Dock = DockStyle.Bottom; this.button2.Dock = DockStyle.Bottom; this.button3.SendToBack(); this.listView1.Visible = true; } private void button2_Click(object sender, EventArgs e) { this.button1.SendToBack(); this.button2.Dock = DockStyle.Top; this.button3.Dock = DockStyle.Bottom; this.listView1.Visible = false; } private void button3_Click(object sender, EventArgs e) { this.button1.Dock = DockStyle.Top; this.button2.Dock = DockStyle.Top; this.button3.Dock = DockStyle.Top; this.button1.SendToBack(); this.listView1.Visible = false; } } }
