Question

我创建了这个名为“CInventory”的类。该类生成一个“有效数据”数组。为了在一个范围内看到这个数组，我试图“粘贴”数组以查看结果。我得到一个“下标超出范围”。该错误出现在简单模块的第6行（cinv.AllocateInventoryData）上。

这是名为CInventory的类模块：

Option Explicit
Private Path As String
Private TextFileNumber As Integer
Private InventoryData() As String

Public Property Get GetInventoryData() As String
    GetInventoryData = InventoryData
End Property

Public Property Let SPath(Text As String)
    Path = Text
End Property

Public Sub AllocateInventoryData()
    Dim ColumnArray() As String
    TextFileNumber = FreeFile
    Dim FileContent As String
    Dim i, j As Integer
    j = 0
    Open Path For Input As TextFileNumber
    FileContent = Input(LOF(TextFileNumber), TextFileNumber)
    Close TextFileNumber
    ColumnArray() = Split(FileContent, vbCrLf)
    For i = LBound(ColumnArray) To UBound(ColumnArray)
        If IsValidRow(ColumnArray(i)) Then
            ReDim Preserve InventoryData(j, 4)
            InventoryData(j, 0) = Left(ColumnArray(i), 8)
            InventoryData(j, 1) = Trim(Mid(ColumnArray(i), 10, 8))
            InventoryData(j, 2) = Trim(Mid(ColumnArray(i), 19, 18))
            InventoryData(j, 3) = Trim(Mid(ColumnArray(i), 57, 2))
            InventoryData(j, 4) = Trim(Mid(ColumnArray(i), 60, 12))
            j = j + 1
        End If
    Next i
End Sub

Private Function IsValidRow(Text As String) As Boolean
    If Left(Text, 6) = "iclorp" Or Left(Text, 5) = "Page:" Or Len(Trim(Text)) < 3 _
    Or Left(Text, 4) = "Site" Or Left(Text, 6) = "------" Then
        IsValidRow = False
    Else
        IsValidRow = True
    End If
End Function

这是我称之为CInventory类（简单模块）的模块

Option Explicit
Sub example()
    Dim cinv As CInventory
    Set cinv = New CInventory
    cinv.SPath = "H:\Joel\invent_2.prn"
    cinv.AllocateInventoryData   '<-- here appears the error
    Worksheets(1).Cells(1, 1) = cinv.GetInventoryData
End Sub

这是答案！过了一会儿，但它按照我想要的方式工作

课程模块'CInventory'

Option Explicit
Private Path As String
Private TextFileNumber As Integer
Private InventoryData() As String
Private UBoundInventoryDataRows As Integer
Private UBoundInventoryDataColumns As Integer

Public Property Get GetUBoundInventoryDataRows() As Integer
GetUBoundInventoryDataRows = UBoundInventoryDataRows
End Property

Public Property Get GetUBoundInventoryDataColumns() As Integer
GetUBoundInventoryDataColumns = UBoundInventoryDataColumns
End Property

Public Property Get GetInventoryData() As String()
GetInventoryData = InventoryData
End Property

Public Property Let SPath(Text As String)
Path = Text
End Property

Public Sub AllocateInventoryData()
Dim tempArray() As String
Dim TempLineArray() As String
Dim ColumnArray() As String
Dim FileContent As String
Dim i, j As Integer
TextFileNumber = FreeFile
j = 0
Open Path For Input As TextFileNumber
FileContent = Input(LOF(TextFileNumber), TextFileNumber)
Close TextFileNumber
ColumnArray() = Split(FileContent, vbCrLf)
For i = LBound(ColumnArray) To UBound(ColumnArray)
If LCase(Left(Trim(ColumnArray(i)), 2)) = "mx" Then
ReDim Preserve tempArray(j)
tempArray(j) = Trim(Left(ColumnArray(i), 9)) & ":" & _
Trim(Mid(ColumnArray(i), 10, 9)) & ":" & _
Trim(Mid(ColumnArray(i), 19, 18)) & ":" & _
Trim(Mid(ColumnArray(i), 37, 20)) & ":" & _
Trim(Mid(ColumnArray(i), 57, 4)) & ":" & _
Trim(Mid(ColumnArray(i), 61, 12)) & ":" & _
Trim(Mid(ColumnArray(i), 73, 9)) & ":" & _
Trim(Mid(ColumnArray(i), 82, 9)) & ":" & _
Trim(Mid(ColumnArray(i), 91, 8)) & ":" & _
Trim(Mid(ColumnArray(i), 99, 6)) & ":" & _
Trim(Mid(ColumnArray(i), 105, 9)) & ":" & _
Trim(Mid(ColumnArray(i), 114, 6)) & ":" & _
Trim(Mid(ColumnArray(i), 120, 4)) & ":" & _
Trim(Mid(ColumnArray(i), 124, 3))
j = j + 1
End If
Next i
'in a normal module we shall transpose this next array.
'I did this in this way because of redim agreement
' "the last dimension only could be re-dimensioned" 
ReDim InventoryData(13, UBound(tempArray))
For i = LBound(tempArray) To 13
For j = LBound(tempArray) To UBound(tempArray)
TempLineArray = Split(tempArray(j), ":")
InventoryData(i, j) = TempLineArray(i)
Next j
Next i
UBoundInventoryDataRows = UBound(InventoryData, 1)
UBoundInventoryDataColumns = UBound(InventoryData, 2)
End Sub

这里是简单模块

Option Explicit
Sub example()
Dim cinv As CInventory
Set cinv = New CInventory
cinv.SPath = "H:\Joel\invent_2.prn"
cinv.AllocateInventoryData
Dim row, column As Integer
row = cinv.GetUBoundInventoryDataRows
column = cinv.GetUBoundInventoryDataColumns
Dim Destination As Range
Set Destination = Range("a1")
Destination.Resize(column, row).Value = Application.Transpose(cinv.GetInventoryData)
Set cinv = Nothing
End Sub

下标超出了Class
