如何在winform中动态添加或删除控件

Answer 1

单击button1在panel上动态新建了多个label，现在想要点击选择某个动态新建的label，按button2，可以把这个label删掉
在button1_Click事件中，创建label，代码：
Label lb1 = new Label();
lb1.Name = "panel"+j;
lb1.BackColor = Color.Transparent;
lb1.BorderStyle = BorderStyle.FixedSingle;
Panel1.Controls.Add(lb1);
为这些label增加Click事件
Label lb1 = new Label();
lb1.Name = "panel"+j;
lb1.BackColor = Color.Transparent;

Answer 2

Form from1 = new Form();
TextBox txt = new TextBox();
txt.Width = 200;
txt.Position = new Point(100, 100);
from1.AddControl(txt);
from1.Show();
