我已经为此战斗了两个星期。基本上，我想比较2个多维数组中的数据。
这是我的第一个数组：
$images = @(Get-ContentLibraryItem |
Select-Object Name, @{n='NameParts'; e={$_.Name -split '-',3}} |
Select-Object Name, @{n='BaseName'; e={$_.NameParts[0]}},
@{n='Version'; e={[version]$_.NameParts[1]}})
输出看起来像这样：
Name BaseName Version
---- -------- -------
sles11sp4_jeos-1234567890 sles11sp4_jeos
sles12sp3-0.0.11 sles12sp3 0.0.11

win2016std_desk-0.3.45 win2016std_desk 0.3.45
win2016std_desk-0.4.56 win2016std_desk 0.3.33
这是我的第二个数组：
$templates = @(get-template |
Select-Object Name, @{n='NameParts'; e={$_.Name -split '-',3}} |
Select-Object Name, @{n='BaseName'; e={$_.NameParts[0]}},
@{n='Version'; e={[version]$_.NameParts[1]}})
输出看起来像这样：

在一天结束时，我正在寻找$templates和$template.basename -eq $image.basename的所有$template.version -eq $image.version并删除其他所有内容。我遇到的问题是，如果我在foreach循环中一次比较它们一次，它们最终将删除所有模板。如何将数组比较在一起，以便可以在新数组中获得所有“好”模板或所有“坏”模板。
这是我的代码的最后一次迭代（该代码无效...没有删除任何内容）。
Foreach ($image in $images){
Foreach ($template in $templates){
if ($template |where-object {$_.basename -eq $image.basename -and $_.version -eq $image.version}){
Write-host "Template Name Matches, next"
}
Else {
Write-host "Image and version do not match, deleting"
Write-log -Message "Remove-template -template $($template.name) -DeletePermanently"
}
}
}
这是有效的最终代码！注意：我需要添加一个switch命令将删除的内容导出到csv，如果switch为true，它将执行删除操作。
$images = @(Get-ContentLibraryItem |
Select-Object Name, @{n='NameParts'; e={$_.Name -split '-',3}} |
Select-Object Name, @{n='BaseName'; e={$_.NameParts[0]}},
@{n='Version'; e={[version]$_.NameParts[1]}})
$templates = @(get-template |
Select-Object Name, @{n='NameParts'; e={$_.Name -split '-',3}} |
Select-Object Name, @{n='BaseName'; e={$_.NameParts[0]}},
@{n='Version'; e={[version]$_.NameParts[1]}})
$goodtemplates = @()
$goodtemplates = $templates |% {compare-object $_ -DifferenceObject $images -property basename,version -excludedifferent -includeequal -passthru | Select Name,BaseName,Version}
$badtemplates = diff $goodtemplates.name $templates.name
Foreach ($badtemplate in $badtemplates){
Write-host "Image and version do not match, deleting"
Remove-template -template $($badtemplate.inputobject) -DeletePermanently -confirm:$false
}
答案 0 :(得分：1)
我认为这可能有效。这应该输出符合您条件的东西：
$templates | foreach-object {
compare-object $_ -ReferenceObject $templates -DifferenceObject $images -property basename,version -excludedifferent -includeequal -passthru | select Name,BaseName,Version
}
这是一个测试：

您自己走在正确的道路上，但是您创建了太多的循环（考虑到Where-Object cmdlet会引发第三个循环）。

'
只需使用If语句：
Foreach ($image in $images){
Foreach ($template in $templates){
if ($template.basename -eq $image.basename -and $template.version -eq $image.version){
Write-host "Template Name Matches, next"
}
Else {
Write-host "Image and version do not match, deleting"
Write-Warning "Remove-template -template $($template.name) -DeletePermanently"
}
}
}
您将看到一些结果，例如：
Image and version do not match, deleting
WARNING: Remove-template -template sles12sp3-0.0.11-infra-dr01 -DeletePermanently
Image and version do not match, deleting
WARNING: Remove-template -template win2016std_desk-0.3.33-infra-dr01 -DeletePermanently
Image and version do not match, deleting
WARNING: Remove-template -template win2016std_desk-0.3.42-infra-dr01 -DeletePermanently
Image and version do not match, deleting
WARNING: Remove-template -template win2012r2std_desk-0.1.23-infra-dr01 -DeletePermanently
...
您也可以使用此Join-Object cmdlet：
$Templates | Join $Images -On BaseName, Version `
-Property @{TemplateName = {$Left.Name}; ImageName = {$Right.Name}}, BaseName, Version
结果：
ImageName TemplateName BaseName Version
