arrays - VBA 第一个数组项始终为空

Question

下面的代码是我从网上找到的几个例子拼凑而成的，我不是VBA专家。

但是 clist 数组中的第一项(以及下拉列表中的第一项)始终为空，我假设它与 redim 有关s，但我想不通。

可能是什么问题？

Private Sub ComboBox1_Change()
    ReDim clist(0)
    'If any value is input
    If ComboBox1.Value <> "" Then
        Dim kword As Variant
        Dim product As Variant
        'For each product description in our sheet table
        For Each product In [Produtos[Descrição]].Rows
            'Keyword search
            For Each kword In Split(ComboBox1.Value, " ")
                If InStr(Replace(product.Value, "", " "), kword) And kword <> "" Then
                    'Issue most likely here
                    ReDim Preserve clist(UBound(clist) + 1) As Variant
                    clist(UBound(clist)) = product.Value
                    Exit For
                End If
            Next kword
        Next product
        ComboBox1.list = clist
        'If found something
        If UBound(clist) > 0 Then
            ComboBox1.DropDown
        End If
    'If no Input just show all products, here it doesn't show a blank item
    Else
        ComboBox1.list = [Produtos[Descrição]].Value2
    End If
End Sub

尝试一下，

    ReDim clist(0)
    For Each product In [Produtos[Descrição]].Rows
        'Keyword search
        For Each kword In Split(ComboBox1.Value, " ")
            If InStr(Replace(product.Value, "", " "), kword) And kword <> "" Then
                'Issue most likely here
                clist(UBound(clist)) = product.Value
                ReDim Preserve clist(UBound(clist) + 1)
                Exit For
            End If
        Next kword
    Next product
    ReDim Preserve clist(UBound(clist) - 1)
