SSRS表达式显示字符串数组

Question

我有以下自定义代码，它在输入字符串中找到给定的字符串并相应地返回字符串数组。

Public Function ConvertCode(ParamValues As String, findString As String) As String()
Dim SrcArray() As String
Dim FndArray() As String
Dim DstArray() As String
Dim i As Integer
Dim j As Integer
Dim k As Integer
SrcArray = Split(ParamValues, ",")
FndArray = Split(FindString,",")
For k = LBound(FndArray) To UBound(FndArray)
For i = LBound(SrcArray) To UBound(SrcArray)
    If (InStr(SrcArray(i), FndArray(k)) > 0) Then
        DstArray(j) = SrcArray(i)
        j = j + 1
    End If
Next i
Next k
ConvertCode  =  DstArray
End Function 

我正在使用SSRS表达式来获取此代码返回的值。

=Join(Code.ConvertCode(Join(Parameters!ProcessingStatus.Value,","),"reject,fail,Reject,Fail"),",")

如果ProcessingStatus中没有匹配的元素，它会正确返回并且只显示匹配的strng，然后它将返回为#Error。请帮帮我。
