vb.net根据一个传入的字符串得到需要使用的类解决方法

vb.net根据一个传入的字符串得到需要使用的类
比方说我传入一个“label”，则生成一个label控件，该怎么实现？
希望各位大大帮个忙。
如果直接传入类型，又该怎么弄。

VB.NET code

'动态添加控件Dim btnNewButton As New ButtonbtnNewButton.Location = New System.Drawing.Point(Me.Location.X, Me.Location.Y)  'Point根据自己情况定Me.Controls.Add(btnNewButton)

VB.NET code
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click        Me.CreateCtr("textbox", "hello", Me.Controls)    End Sub    Private Sub CreateCtr(ByVal ctrTypeName As String, ByVal text As String, ByVal ctrCollection As ControlCollection)        Dim a As Reflection.Assembly = GetType(Button).Assembly        Dim ctrType As Type = a.GetType(String.Concat(a.GetName.Name, ".", ctrTypeName), True, True)        Me.CreateCtr(ctrType, text, ctrCollection)    End Sub    '不考虑位置,事件,名称等    Private Sub CreateCtr(ByVal ctrType As Type, ByVal text As String, ByVal ctrCollection As ControlCollection)        Dim ctr As Control = CType(Activator.CreateInstance(ctrType), Control)        ctr.Text = text        ctrCollection.Add(ctr)    End Sub
