    chckJun.CheckedChanged,
   chckJul.CheckedChanged,
    chckAug.CheckedChanged,
chckOct.CheckedChanged,
  chckNov.CheckedChanged,
   chckDec.CheckedChanged


    'get all checkboxes
    Dim Months = Controls.OfType(Of CheckBox)().ToArray()
    'Get the number of checked CheckBoxes.
    Dim checkedBoxCount = Months.Count(Function(cb) cb.Checked)
    'Unchecked CheckBoxes should be enabled if and only if the number of checked CheckBoxes is less than the maximum number allowed.
    Dim enableUncheckedBoxes = checkedBoxCount < 2
    'Get the unchecked CheckBoxes.
    Dim uncheckedBoxes = Months.Where(Function(cb) Not cb.Checked)

我需要获取两个复选框的名称

你已经有了一个循环;使用它：

For Each CheckBox In CheckBoxArray
    If CheckBox.Checked = True Then
        Debug.Print(CheckBox.Name)
    End If
Next

我可以遍历我的控件并检索其指定属性的名称吗？
