通过控件的名称来控制控件,真郁闷，报错了，帮忙看看

[doudouheweigege]

我想通过控件名称来控制控件，可运行到
Dim mycontrol1 As Label = CType(f.GetValue(Me), Label)
就出错了，我也不知道什么原因，忘高手帮忙

Imports System.Reflection
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim t As Type = Me.GetType
        Dim f As FieldInfo = t.GetField("Label1", BindingFlags.NonPublic Or BindingFlags.Instance Or BindingFlags.Public)

        Dim mycontrol1 As Label = CType(f.GetValue(Me), Label)
        mycontrol1.BackColor = Color.Blue
    End Sub
