【问题描述】：
我在这里陷入了僵局。我开始使用 PowerShell 编写脚本来处理将共享数据源设置为文件夹的所有报告。
我的逻辑： 对于文件夹中的每个报告和报告的每个数据源：
如果数据源名称与要替换的名称匹配 1：如果它的引用已经设置：用共享的替换它 2：如果它是自定义数据源：将其替换为共享数据源 3：如果它的引用为空：用共享的替换它
案例 1 完美运行，而案例 2 和案例 3 失败。我不明白为什么在第一种情况下它接受单个元素，而在另一种情况下，它没有告诉我它需要一个数组：
Impossible de convertir l'argument «DataSources» (valeur «SSRS.ReportingService2010.DataSource») de «SetItemDataSources
» en type «SSRS.ReportingService2010.DataSource[]»: «Impossible de convertir la valeur «
SSRS.ReportingService2010.DataSource» du type «SSRS.ReportingService2010.DataSource» en type «
SSRS.ReportingService2010.DataSource[]».»
Au caractère Ligne:87 : 1
+ $proxy.SetItemDataSources($ssrsItem.Path, $newDataSource);
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodException
+ FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument
这是我想出的全部代码（它很冗长，但我认为它有助于提高可读性）：
# Usage : SetConnection "msbireports" "/2134_DELIVRI/Test/PS1" "EDUCFI_SSAS" "/2134_DELIVRI/Test/PS1/Datasources/EDUCFI_SSAS.rds" true
function SetConnection(
$reportServerName = $(throw "reportServerName is required."),
$serverPath = $(throw "serverPath is required."),
$connectionName = $(throw "connectionName is required."),
$toConnection = $(throw "toConnection is required."),
$replaceCustom = $(throw "replaceCustom is required.")
)
{

Write-Host "> Getting Items from $serverPath"

Write-Host ""

Foreach($ssrsItem in $items)

if ($dsItem.Item.Reference -eq $toConnection)

$proxy.SetItemDataSources($ssrsItem.Path, $dsItem);
Write-Host " Done!" -ForegroundColor Green
Write-Host ""
}
}
else
{

# Check for Custom Datasource (has a property called Enabled which ShareDatasource has not)
if($dsItem.Item.PSObject.Properties.Match('Enabled').Count)
{
if ($replaceCustom -eq "replace")
{
Write-Host ">> Changing Custom Connection $connectionName to a Shared one pointing to $toConnection..." -ForegroundColor Gray
$newDataSource = New-Object("SSRS.ReportingService2010.DataSource")
$newDataSource.Name = $connectionName
$newDataSource.Item = New-Object ("SSRS.ReportingService2010.DataSourceReference")
$newDataSource.Item.Reference = $toConnection
$proxy.SetItemDataSources($ssrsItem.Path, $newDataSource);
Write-Host " DOES NOT WORK !" -ForegroundColor RED
Write-Host ""
}
else
{
Write-Host ">> Nothing done : $connectionName set up as a Custom Connection, but was told not to change it" -ForegroundColor Gray
Write-Host ""
}
}

{
Write-Host ">> OF TYPE SHARED... But not really ???"
$newDataSource = New-Object("SSRS.ReportingService2010.DataSource")
$newDataSource.Name = $connectionName
$newDataSource.Item = New-Object ("SSRS.ReportingService2010.DataSourceReference")
$newDataSource.Item.Reference = $toConnection
$proxy.SetItemDataSources($ssrsItem.Path, $newDataSource);

}
}
}
}
SetConnection "msbireports" "/2134_DELIVRI/Test/PS1" "EDUCFI_SSAS" "/1446_EDUCFI/Datasources/EDUCFI_SSAS" "replace"
这让我发疯了。我也尝试以不同的方式执行此操作，即构建一个 DataSources 数组，并在报告处理结束时将其推送到 SetItemDataSources 但每次这两种情况都失败了，出现一个奇怪的错误，告诉我它无法转换一个数据源到..一个数据源。 （？！）
我的理智恳求您的帮助！
