使用 PowerShell 创建 SSRS 数据驱动订阅

Question

编辑：将整个转换后的 c# 添加到 PowerShell 中有问题

我正在尝试将 MSDN C# 代码转换为 PowerShell 脚本。 这是 MSDN link

我几乎完成了转换，但我在最后一行遇到了一些问题。

这是完整的错误消息：使用“7”参数调用“CreateDataDrivenSubscription”的异常：“生成 XML 文档时出错。”

下面是创建数据驱动订阅的第 7 个参数的代码 sn-p。

这是 PowerShell 脚本：

$Parameters | Add-Member -type NoteProperty -Name $EMPID.ParameterName -Value $EMPID.FieldAlias

$ReportYear = New-Object $ParameterValue
$ReportYear.Name = "ReportYear"
$ReportYear.Value = "2017"

$Parameters | Add-Member -type NoteProperty -Name $ReportYear.Name -Value $ReportYear.Value

$ReportMonth = New-Object $ParameterValue

$ReportMonth.Name = "ReportMonth"
$ReportMonth.Value = "6"

$Parameters | Add-Member -Type NoteProperty -Name $ReportMonth.Name -Value $ReportMonth.Value


$SubscriptionID = $objWebServerProxy.CreateDataDrivenSubscription($Report,$Settings,$arrDataRetrievalPlan,$Description,$EventType,$MatchData,$Parameters)

这是 C# 代码

ParameterValueOrFieldReference[] parameters = new ParameterValueOrFieldReference[3];

ParameterFieldReference empID = new ParameterFieldReference(); // Data-driven.
empID.ParameterName = "EmpID";
empID.FieldAlias = "EmpID";
parameters[0] = empID;

ParameterValue reportYear = new ParameterValue();
reportYear.Name = "ReportYear";
reportYear.Value = "2004";
parameters[1] = reportYear;

ParameterValue reportMonth = new ParameterValue();
reportMonth.Name = "ReportMonth";
reportMonth.Value = "6"; // June
parameters[2] = reportMonth;

try
{
    string subscriptionID = rs.CreateDataDrivenSubscription( 
report, settings, dataRetrieval, description, eventType, matchData, parameters);

您能告诉我转换过程中我错过了哪些地方吗？

这是我转换后的整个脚本。

我不确定您创建 ParameterValue 实例的方式是否有效 - 由于缺少 $ParameterValue 声明，我无法确定，但这很可能会导致问题。 您可能想尝试更多类似的方法：

$reportServerUri = "http://localhost/reportserver/ReportService2010.asmx?wsdl"
$rs = New-WebServiceProxy -Uri $reportServerUri -UseDefaultCredential -Namespace "SSRS"

# Note the difference, here we use the type generated when creating the webservice proxy:
$ReportYear = New-Object SSRS.ParameterValue 
$ReportYear.Name = "ReportYear"
$ReportYear.Value = "2017"

请参阅我的blog post here 以获取快速教程。

编辑 要查明错误是CreateDataDrivenSubscription 的哪个参数，请尝试用$null 替换一个或多个参数 - 根据方法的文档确定它可能是无效的，但只有在调用成功发送到服务器后才会进行空检查并反序列化。

换句话说，如果用$null 替换$Parameters 参数不会抛出“错误生成XML 文档”，那么错误就在$Parameters 参数中：

$SubscriptionID = $objWebServerProxy.CreateDataDrivenSubscription($Report,$Settings,
           $arrDataRetrievalPlan,$Description,$EventType,$MatchData,$null)
