数组到Excel范围-Java 学习之路

我是VBA的新手，并尝试通过数组UDF将数组写入excel范围 .

我试图将数组输出到公式所在的最大行数 . 我正在使用Microsoft Scripting Library作为字典，如果这很重要 . 使用excel中的数组公式（CTRL Shift Enter），如何将数组的大小调整为放置公式的范围，然后将数组放入单元格中？我希望细胞上的公式为= test（“G1：J20”），公式将放在单元格A1：B20中 .

代码：功能测试（ByVal inputRange As Range）As Variant Dim Cell As Variant Dim D As Dictionary Dim Arr（）As Variant Dim i As Long Set D = New Dictionary

' Remove duplicates
For Each Cell In inputRange
    If D.Exists(CStr(Cell.Value)) = False Then
        D.Add CStr(Cell.Value), 1
    Else
        D.Exists (Cell.Value)
        D.Item(Cell.Value) = D.Item(Cell.Value) + 1
   End If
Next
D.Remove vbNullString

Redim Arr(0 To Application.Max(D.Count, Application.Caller.Cells.Count))

'Fill the array with the keys from the Dictionary
For i = 0 To D.Count - 1
    Arr(i) = D.Keys(i)
Next i

test = Application.Transpose(Arr)
End Function

要读取和写入数组到单元格，您需要一个2D数组 . 例如：

Dim data() as Variant, N as Integer, M as Integer
' Say you want a 100×50 array
N = 100 : M = 50
ReDim data(1 to N, 1 to M)
' Fill data()
Range("A1").Resize(N,M).Value = data

或者只是读取值

Dim data() as Variant, N as Integer, M as Integer, i as Integer, j as Integer
data = Range("A1:AX100").Value
N = UBOUND(data,1) : M = UBOUND(data,2)
For i = 1 to N
    For j = 1 to M
        Debug.Print(data(i,j))
    Next j
Next i

这是一个将数组放入工作表范围的方法，这是你的意思吗？

Sub test()
    Dim v(0 To 2, 0 To 2) As Variant
    Dim r As Range
    'fill the array with values
    populate v
    'range must be same dimensions as array, in this case 3x3
    Set r = ActiveSheet.Range("A1:C3")
    'this simply puts array into range values
    r.Value2 = v
End Sub

Function populate(v As Variant)
    For i = 0 To 2
        For j = 0 To 2
            v(j, i) = i * j * j - i + 2
        Next j
    Next i
End Function

但是，由于您已经遍历字典中的值，为什么不直接将值写入工作表？您可以通过交换行和列索引来模仿转置

Sub test()
    Dim dict As Dictionary
    Set dict = New Dictionary
    'fill dictionary with values
    populate dict
    'loop through dictionary, and add items to worksheet
    For i = 0 To dict.Count - 1
        ActiveSheet.Cells(1, i + 1).Value = dict.Keys(i)
        ActiveSheet.Cells(2, i + 1).Value = dict.Items(i)
    Next i
End Sub

Function populate(dict As Dictionary)
    dict.Add "help", "me"
    dict.Add "I'm", "lost"
    dict.Add "everything", "1"
    dict.Add "or", "0"
End Function
