如何创建一个 Radiobutton 数组？

  • 772

有一个表格。上面有 4 个单选按钮。
我正在尝试创建一个数组：

Dim radioButtons As RadioButton {
 RadioButton1,
 RadioButton2,
 RadioButton3,
 RadioButton4
}

然后我尝试在循环中迭代数组：

For i = 0 To ubound(radiobuttons)
   radioButtons(i).Text = ...
Next

但是在循环中，会发生错误。
如何正确实施这个想法？

    比如这样。

        Dim buttons As RadioButton() = New RadioButton(3) {
            RadioButton1,
            RadioButton2,
            RadioButton3,
            RadioButton4}

    For i = 0 To UBound(buttons)
        radioButtons(i).Text = "text"
    Next

    但我会这样做，列表比数组方便得多。

        Dim radioButtons As New List(Of RadioButton)

    radioButtons.Add(RadioButton1)
    radioButtons.Add(RadioButton2)
    radioButtons.Add(RadioButton3)
    radioButtons.Add(RadioButton4)

    For Each button As RadioButton In radioButtons
        button.Text = "text"
    Next
