Question

有谁知道如何从嵌入在XML中的JSON中获取值并将其分配给SSIS中的变量？

我有一个创建具有JSON值的XML的作业，如下所示：

<string>
{"result_code":1,"result_message":"All calling list successfully retrieved records number","total_records":0,"total_processed":0,"total_excluded":0,"ResultCSV":null,"number_callinglist_records":6015}
</string>

下面是我用来从嵌入式JSON中获取"number_calling_list"值并将其分配给字符串变量的脚本：

Dim totalCount As String = ""
If FileContents.Contains("number_callinglist_records") = True Then
    totalCount = Dts.Variables("number_callinglist_records").Value
End If


If FileContents.Contains("number_callinglist_records") = True Then
    EmailMessage = "List count has been successfully, see attached file for details " + totalCount
Else : EmailMessage = "List count has been failed, please see attachment for details"

它不起作用，并在运行时显示以下错误消息：

Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException：元素在集合中找不到。尝试时会发生此错误在执行期间从容器上的集合中检索元素包裹和元素不存在。

有谁知道为什么会发生这种情况以及如何从嵌入式JSON中获取"number_callinglist_records"值？

您的Dts.Variables引用看起来不对。我会改变：

Dts.Variables("number_callinglist_records").Value

到

Dts.Variables("User::number_callinglist_records").Value
