字典和函数：未定义用户定义的类型

Question

我已经在Excel VBA中键入以下代码：该函数应根据特定列部分中的唯一值创建一个字典。

Function CreateDictForFactors(xcord As Integer, ycord As Integer, length As Integer) As Dictionary
Dim Dict As Dictionary
Set Dict = New Dictionary
Dim i As Integer
For i = 0 To length - 1
If Not Dict.Exists(Cells(xcord + i, ycord)) Then
            Dict.Add Cells(xcord + i, ycord), 0
            End If
Next i
Set CreateDictForFactors = Dict
End Function

Sub test2()
Dim dict1 As Dictionary
Set dict1 = CreateDictForFactors(7, 6, 12)

End Sub

我发现此代码是字典和函数的示例：

Sub mySub()
    dim myDict as Dictionary
    set myDict = myFunc()
End Sub

Function myFunc() as Dictionary
    dim myDict2 as Dictionary
    set myDict2 = new Dictionary
            'some code that does things and adds to myDict2'
    set myFunc=myDict2
End Function

但是，当我尝试运行makro test2 ，会显示错误消息：

用户定义类型未定义

谁能说出我在哪里犯错了？ 先感谢您

Answer 1

G'day，

您是否添加了“ Microsoft Scripting Runtime”作为对项目的引用？

完成此操作后，将dict声明为Scripting.Dictionary，如下所示：

Dim dict As Scripting.Dictionary

您可以如下创建对象：

Set dict = New Scripting.Dictionary

这是一个描述字典用法的好网站：

希望这可以帮助。

Answer 2

您也可以像这样晚绑定代码：

Function CreateDictForFactors(xcord As Integer, ycord As Integer, length As Integer) As Dictionary
Dim Dict As Object
Set Dict = CreateObject("Scripting.Dictionary")
Dim i As Integer
For i = 0 To length - 1
If Not Dict.Exists(Cells(xcord + i, ycord)) Then
            Dict.Add Cells(xcord + i, ycord), 0
            End If
Next i
Set CreateDictForFactors = Dict
End Function

Sub test2()
Dim dict1 As Object
Set dict1 = CreateDictForFactors(7, 6, 12)

End Sub

请注意，这两种方法均不适用于Mac。
