以编程方式向面板添加控件

我正在尝试将一组四个单选按钮添加到表单中。还有其他的单选按钮,所以我将它们放在面板上进行分组。但是,使用下面的方法,我只需将面板添加到表单中,而不使用单选按钮…我在这里做错什么了吗?

Dim arrRButton(3) As RadioButton
arrRButton(0) = New RadioButton
arrRButton(1) = New RadioButton
arrRButton(2) = New RadioButton
arrRButton(3) = New RadioButton           

With arrRButton(0)
  .AutoSize = True
  .Checked = True
  .Location = New System.Drawing.Point(77, 139)
  .Name = "RadioButton5"
  .Size = New System.Drawing.Size(55, 17)
  .TabIndex = 48
  .TabStop = True
  .Text = "NEAR"
  .UseVisualStyleBackColor = True
End With
'.... etc

'Panel2
Dim Panel2 As New Panel
With Panel2
  .Controls.Add(arrRButton(0))
  .Controls.Add(arrRButton(1))
  .Controls.Add(arrRButton(2))
  .Controls.Add(arrRButton(3))
  .Location = New System.Drawing.Point(61, 130)
  .Name = "Panel2"
  .Size = New System.Drawing.Size(300, 24)
End With

Me.Controls.Add(Panel2)
