请教.如何向panel添加控件数组

请教如何在panel动态添加label控件数组  在网上了找了很多教程..  都是向窗体中动态添加.如下类
这是VB.NET的一个类
Public Class ButtonArray

    Inherits System.Collections.CollectionBase
    Private ReadOnly ParentForm As System.Windows.Forms.Form
    Public Sub New(ByVal pForm As System.Windows.Forms.Form)
        ParentForm = pForm
    End Sub
    Default Public ReadOnly Property Item(ByVal index As Integer) As System.Windows.Forms.Button
        Get
            Return Me.List.Item(index)   ' ButtonArray的List 属性从CollectionBase 继承
        End Get
    End Property
    Public Sub AddItem()
        Dim btnItem As New System.Windows.Forms.Button()
        Me.List.Add(btnItem)
        ParentForm.Controls.Add(btnItem)                  '向窗体中增加控件
        btnItem.Tag = Me.Count                            'Count属性从CollectionBase 继承
        btnItem.Top = Me.Count * 30
        btnItem.Left = 200
        btnItem.Text = "Button" & Me.Count.ToString
        AddHandler btnItem.Click, AddressOf btnItem_Click '绑定事件处理程序
    End Sub
   Public Sub RemoveItem()
        If Me.Count > 0 Then
            ParentForm.Controls.Remove(Me(Me.Count - 1))
            Me.List.RemoveAt(Me.Count - 1)
        End If
    End Sub
   Public Sub btnItem_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        '在这里编写控件数组对点击事件的响应
        '例如：
        MsgBox("点击：" & sender.GetType().ToString & CType(CType(sender, Button).Tag, String))
    End Sub
End Class

此类可以向窗休中添加..但不知如何向Panel中添加

--------------------编程问答-------------------- Private ReadOnly ParentForm As System.Windows.Forms.panel
    Public Sub New(ByVal pForm As System.Windows.Forms.panel)
        ParentForm = pForm
    End Sub
以修改成相应的这样..
用dim aaa as ButtonArray (me),,,在窗体上动态添加Button就可以
用dim aaa as ButtonArray (panel1),,, 这样为什么就不行呢... --------------------编程问答-------------------- 把ParentForm.Controls.Add(btnItem)换成Panel.Controls.Add(btnItem)  就行啦.
容器控件使用方式都是一样的. --------------------编程问答-------------------- 不行啊..我试过了..从 Dim la As New ButtonArray(panel1)  进类时.就没能把panel1传到类里面去  用me 就能传进去

补充：.NET技术 ,  C#
