我正在尝试使用.item(). 我要做的是在收集功能中收集数据并通过infncPopCcyLst访问它以获取行号。这是一个测试，看看我是否可以在我的集合中存储多个数据并通过. 但是，我收到 VBA 运行时错误“5”。有人会指导我做错了什么吗？谢谢你。.item(1)cbSortCcy.item()
以下是我的代码。
类模块：clsSngGenUtl
Private prpSngStrVal As String
Private prpSngRowNum As Long
Private prpSngClmNum As Long
'++ Define properties
'== String row number
Public Property Get SngStrVal() As String
SngStrVal = prpSngStrVal
End Property
Public Property Let SngStrVal(ByRef varStrVal As String)
prpSngStrVal = varStrVal
End Property
'++ Define properties
'== Scalar row number
Public Property Get SngRowNum() As Long
SngRowNum = prpSngRowNum
End Property
Public Property Let SngRowNum(ByVal varRowNum As Long)
prpSngRowNum = varRowNum
End Property
'++ Define properties
'== Single column number
Public Property Get SngClmNum() As Long
SngClmNum = prpSngClmNum
End Property
Public Property Let SngClmNum(ByRef varClmNum As Long)

下面是我的收藏类：clsColCcySrt
'++ Declare variables
Private prpColCcySrt As Collection
'++ Define properties
Public Property Get ColCcySrt() As Collection
Set ColCcySrt = prpColCcySrt
End Property
Public Property Set ColCcySrt(varColCcy As Collection)
Set prpColCcySrt = varColCcy
End Property
Public Function fncGetCcyRow(ByRef varStrVal As String) As Long
On Error GoTo Exception
Dim clsSngGen As clsSngGenUtl
Dim varRowNum As Long
varRowNum = 0
For Each clsSngGen In Me.ColCcySrt
varRowNum = clsSngGen.SngRowNum()
Next clsSngGen
'== Return value
fncGetCcyRow = varRowNum
ExitHere:
Exit Function
Exception:
If fncGetCcyRow = 0 Then
MsgBox "Exception: Value is <" & fncGetCcyRow & ">."
End If
Resume ExitHere
End Function
`
用于填充数组的“常规”模块：fncPopFxLst
`
Public Function fncPopCcyLst(ByRef varWbName As String, ByRef varWsName As String, ByRef varCcyTyp As String) As Collection
Dim clnColCcy As Collection
Dim clsArrGen As clsArrGenUtl
Dim clsSngGen As clsSngGenUtl
Dim varWbName As Workbook
Set clnColCcy = New Collection
'== Start collecting items
Set clsSngGen = New clsSngGenUtl
Set varWbName = ThisWorkbook
clsSngGen.SngStrVal = "Reuters"
clsSngGen.SngRowNum = clsSngGen.fncGetRowNum(varWbName, varWsName, 1)
clnColCcy.Add clsSngGen
Set fncPopCcyLst = clnColCcy
End Function
`
最后，子程序`
Private Sub cbSortCcy()
Dim clsColCcy As clsColCcySrt
Dim varDirPth As String
Dim varCcySrc As String
Dim varWsStrg As String
Dim varWbStrg As String
varDirPth = tbDirectoryName & "\" & tbFileName
varCcySrc = "Currency"
varWsStrg = "List"
varWbStrg = varDirPth
Set clsColCcy = New clsColCcySrt
Set clsColCcy.ColCcySrt = fncPopCcyLst(varWbStrg, varWsStrg, varCcySrc)
'Debug.Princ clsColCcy.fncGetCcyRow("Reuters")
Debug.Print clsColCcy.ColCcySrt.Item(1)
End Sub
`
