多值參數作爲SSRS中的VBScript函數輸入

Question

我試圖修改下面的代碼，它爲報告文件中的查詢提供了值。如果存在有限數量的值，則舊的方法工作，對於任意數量的值，修改應該是通用的。

<Value>=Switch(Parameters!TagHum.Count-20=1, Parameters!TagHum.Value(0) 
,Parameters!TagHum.Count-20=2, Parameters!TagHum.Value(0) & ";" & Parameters!TagHum.Value(1) 
,Parameters!TagHum.Count-20=3, Parameters!TagHum.Value(0) & ";" & Parameters!TagHum.Value(2) & ";" & Parameters!TagHum.Value(1)

) </Value> 

它可以通過循環來解決，但SSRS不支持週期，所以我想我可以包括VBS與功能的文件是這樣的：

Public Shared Function TagTempHum_parse(Param_count,Param_values) 
    Dim arr1() 
    Dim result 
    Dim TagCount = Param_count - 20 
    Dim i = 0 
    For i = 1 To TagCount 
     result = result & Param_values(i) & ";" 
    Next 
    result = Left(result, Len(result) - 1) 
    TagTempHum_parse = result 
    End Function 

，並在SSRS調用這個函數：

<Value> 
=Code.TagTempHum_parse(Parameters!TagHum.Count,Parameters!TagHum.Value) 
</Value> 

我的第一個問題是：這種方法甚至有可能嗎？ 第二個問題：我需要將所有參數！TagHumValue值傳遞給函數，當我不知道有多少個參數時，我該如何做到這一點？

對不起，如果我的問題是愚蠢的，我在SSRS新。對任何幫助感到高興。謝謝。

您是否試圖將參數選擇置於單個字符串中？

您可以使用JOIN 到把它們放在一個單一的文本行：

=Join(Parameters!TagHum.Value, ";")
