我在vb.net中设计程序时遇到这样一个问题：错误 1 Handles 子句要求一个在包含类型或它的某个基类型中定义

程序如下： Private Sub rad加_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Rad加.CheckedChanged,
Rad减.CheckedChanged, Rad乘.CheckedChanged, Rad除.CheckedChanged
Select Case True
Case Rad加.Checked
Lbl运算符.Text = "+"
Case Rad减.Checked
Lbl运算符.Text = "-"
Case Rad乘.Checked
Lbl运算符.Text = "X"
Case Rad除.Checked
Lbl运算符.Text = "÷"
End Select
txt结果.Focus()

End Sub

教教大哥大姐，我该怎么处理。

If sender.checked = True Then
Select Case sender.name
Case "Rad加"
Lbl运算符.Text = "+"
Case "Rad减"
Lbl运算符.Text = "-"
Case "Rad乘"
Lbl运算符.Text = "X"
Case "Rad除"
Lbl运算符.Text = "÷"
End Select
txt结果.Focus()
end if
