Question

这是数据类型转换问题。

我正在尝试从SCCM中获取计算机的名称并将其提供给SCCM报告。报告命令行开关接收哈希表，其中变量必须命名为“计算机名”。值是计算机名称。

ex. $computer = @{"Computer Name" = "MyComp01"}

输出Commandlet示例（从SCCM获取计算机名称）这样可以。

$unknownoutputtype = Get-CMDevice -CollectionName "My Collection Computers" | select @{N="Computer Name";E={$_.Name}}

--Output--

Computer Name
-------------
MyComp01
MyComp02
MyComp03
MyComp04
MyComp05
MyComp06

PS> $unknownoutputtype.gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Object[]                                 System.Array

接收Commandlet示例（处理查询）这有效：

$computer = @{"Computer Name" = "MyComp01"}
invoke-cmreport -ReportPath "Software - Companies and Products/Software registered in Add Remove Programs on a specific computer"  -reportparameter $Computer -OutputFormat excel

我需要输出“Get-CMDevice”行作为下面的类型。

PS> $Computer.gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Hashtable                                System.Object

我失败的尝试

PS> Get-CMDevice -CollectionName "My Collection Computers" |select @{N="Computer Name";E={$_.Name}} | Foreach-object {invoke-cmreport -ReportPath "Software - Companies and Products/Software registered in Add Remove Programs on a specific computer" -SiteCode "MySite" -reportparameter $_ -OutputFormat Excel}

错误输出：

Invoke-CMReport : Cannot bind parameter 'ReportParameter'. Cannot convert value "@{Computer Name=MyComp01}" to type "System.Collections.Hashtable". Error: "Cannot convert the "@{Computer Name=MyComp01}" value of type
"Selected.Microsoft.ConfigurationManagement.ManagementProvider.WqlQueryEngine.WqlResultObject" to type "System.Collections.Hashtable"."

Answer 1

Select-Object将始终输出PSCustomObject，而不是哈希表。

在调用ForEach-Object之前，只需在Invoke-CMReport正文中构建哈希表：

Get-CMDevice -CollectionName "My Collection Computers" |Select-Object -ExpandProperty Name | Foreach-object {
    $ReportParameter = @{ 'Computer Name' = $_ }
    invoke-cmreport -ReportPath "Software - Companies and Products/Software registered in Add Remove Programs on a specific computer" -SiteCode "MySite" -reportparameter $ReportParameter -OutputFormat Excel
}

PowerShell将输出转换为哈希表数组（数据类型转换）
