更好的方法可能是跟踪您创建的控件（例如在集合中），并使用它来删除它们。
这样，您的代码就不会绑定到名称格式，并且也可以应用于其他控件类型。

Private cbxs As Collection

Private Sub UserForm_Initialize()
    Set cbxs = New Collection
End Sub

' Remove all dynamicly added Controls
Private Sub btnRemove_Click()
    Dim i As Long
    Do While cbxs.Count > 0
        Me.Controls.Remove cbxs.Item(1).Name
        cbxs.Remove 1
    Loop
End Sub

' Add some Controls, example for testing purposes
Private Sub btnAdd_Click()
    Dim i As Long
    Dim chkBox As Control
    For i = 1 To 10
        Set chkBox = Me.Controls.Add("Forms.CheckBox.1", "SomeRandomName" & i)
        chkBox.Top = 40 + i * 20
        chkBox.Left = 20
        cbxs.Add chkBox, chkBox.Name  '- populate tracking collection
    Next

    ' Demo that it works for other control types
    For i = 1 To 10
        Set chkBox = Me.Controls.Add("Forms.ListBox.1", "SomeOtherRandomName" & i)
        chkBox.Top = 40 + i * 20
        chkBox.Left = 60
        cbxs.Add chkBox, chkBox.Name
    Next

End Sub

假设没有其他以“Checkbox”开头的控件名称，

For Each cont In Me.Controls
    If InStr(cont.Name, "Checkbox") = 1 Then
        Me.Controls.Remove cont.Name
    End If
Next cont

如果你已经知道了控件的名称、类型和数量，为什么要使用双循环呢？
注意，只有在运行时创建的控件才能被删除。

'the following removes all controls created at runtime
Dim i As Long
On Error Resume Next
With Me.Controls
    For i = .Count - 1 to 0 step -1
        .Remove i
    Next i
End With
Err.Clear: On Error GoTo 0

对于您的案例：'如果所有命名都正确

Dim j&
For j = 1 To NumControls
    Me.Controls.Remove "Checkbox" & j
Next j

另一种方法你可以尝试

Me.controls.clear ' from https://learn.microsoft.com/en-us/office/vba/Language/Reference/User-Interface-Help/clear-method-microsoft-forms

为控件添加一个检查似乎解决了这个问题。不知道为什么，但它确实有效。

Dim j As Integer
'Remove all dynamically updated checkboxes
For Each cont In Me.Controls
    If TypeName(cont) = "CheckBox" Then
        For j = 1 To NumControls
            If cont.Name = "Checkbox" & j Then
                Me.Controls.Remove cont.Name
                Exit For
            End If
        Next j
    End If
Next cont

我使用命令按钮重写了原始代码，只添加了“Me.Controls.Count”而不是“NumControls”，并将“Cont”定义为控件。它似乎对我有效。请让我知道这是否适合你：
-->

On Error Resume Next
Dim Cont As Control
Dim C As Integer
'Remove all dynamically updated checkboxes
For Each Cont In Me.Controls
    For C = 1 To Me.Controls.Count
    If Cont.Name = "CommandButton" & C Then
        Me.Controls.Remove ("CommandButton" & C)
    End If
    Next C
Next Cont

选择保留哪些控件和删除哪些控件的另一种方法是使用.Tag属性。这允许在添加控件时对其进行一些精细控制，例如通过使用.Tag作为位字段。
创建时：

With Me.Controls.add("Forms.Label.1", Visible:=True)
{code}
    .Tag = 1
{more code}

到了整理的时候：

For Each C In Me.Controls
    If C.Tag = 1 Then Me.Controls.Remove C.Name
Next
