我如何知道在多选Microsoft Access列表框中单击了哪个项目？

Private Sub ListBox1_Click()
    Dim selectedIndex As Integer
    selectedIndex = ListBox1.ListIndex
    MsgBox "选中的项目索引为：" & selectedIndex
End Sub

Private Sub ListBox1_Click()
    Dim selectedColumn As Integer
    selectedColumn = ListBox1.Column
    MsgBox "选中的项目所在列为：" & selectedColumn
End Sub

Private Sub ListBox1_Click()
    Dim selectedValue As Variant
    selectedValue = ListBox1.Value
    MsgBox "选中的项目的值为：" & selectedValue
End Sub

Private Sub ListBox1_Click()
    Dim boundColumn As Integer
    boundColumn = ListBox1.BoundColumn
    MsgBox "选中的项目的绑定列为：" & boundColumn
End Sub
