VBA：我想将私有类模块变量值传递给公共变量

Question

我有来自数据提供程序的API，它使用类模块发送数据请求，然后处理请求。我在类模块的最后进程代码（TempTickers）中有一个字符串数组，并希望将此数组传递给现有的公共变​​量（Tickers）。

Option Explicit

Dim bbControl As New BB_API_Port

Public f1Ticker, f2Ticker, f1Type, f2Type As String
Public Tickers() As String

Sub BB_Pull_Portfolio()

Dim sSecurity() As String
Dim sFields() As Variant
Dim sOverrideField As String
Dim sOverrideValue As String

ReDim sSecurity(0 To 0) As String
ReDim sFields(0 To 0) As Variant
ReDim Tickers(0 To 0) As String

sSecurity(0) = f1Ticker
sFields(0) = "PORTFOLIO_MPOSITION"
sOverrideField = "REFERENCE_DATE"
sOverrideValue = Format(Range("Date_1").Value, "YYYYMMDD")

bbControl.PortRequest sSecurity, sFields, sOverrideField, sOverrideValue

End Sub
