Add label to Panel programmatically

问题:

So I have a form, and I want to add some Panels with some controls(labels, and radiobuttons) when the form loads.
And I want to do it from the code, of course(it's for making an application with tests, and the questions will be random)
This is what I have done till now:

List<Panel>ls=new List<Panel>();  private void VizualizareTest_Load(object sender, EventArgs e) {     for (int i = 0; i < 4; i++)     {         Panel pan = new Panel();         pan.Name = "panel" + i;         ls.Add(pan);         Label l = new Label();         l.Text = "l"+i;         pan.Controls.Add(l);         pan.Show();     }  } 

But it doesn't show anything on the form.

回答1:

Add the panel just created to the Form.Controls collection

private void VizualizareTest_Load(object sender, EventArgs e) {     for (int i = 0; i < 4; i++)     {         Panel pan = new Panel();         pan.Name = "panel" + i;         ls.Add(pan);         Label l = new Label();         l.Text = "l"+i;         pan.Location = new Point(10, i * 100);         pan.Size = new Size(200, 90);  // just an example         pan.Controls.Add(l);         this.Controls.Add(pan);      } }
