循环访问Azure对象并过滤标记

Question

我有一组Azure对象（虚拟机，数据仓库或Analysis Services），我想循环遍历该集合，但也过滤掉具有特定标记的对象。

例如，让所有不的Analysis Services都有一个名为＆＃34; Environment＆＃34;的标签。价值＆＃34;生产＆＃34;。

如何指定Where-Object过滤器（尝试多种方法但未成功）

cls

# Login to Azure
#Login-AzureRmAccount | Out-Null 

# Selecting the right subscription
#Select-AzureRmSubscription -SubscriptionName "MySubscription" | Out-Null 


# Get all my Analysis Services, but leave out those with the tag Environment=Production
$AnalysisServicesServers = Get-AzureRmAnalysisServicesServer | Where-Object {$_.Tag -notcontains @{Environment="Production";}}

# Loop Through the collection and to something
foreach ($AnalysisServicesServer in $AnalysisServicesServers)
{
    $AnalysisServicesServer                                                      # Show all properties
    Write-Host "1 Name $($AnalysisServicesServer.Name)"                          # Show Name
    Write-Host "2 Tags count [$($AnalysisServicesServer.Tag.Keys.Count)]"        # Show # of tags
    Write-Host "3 Tags Values [$($AnalysisServicesServer.Tag.Values)]"           # Show values
    Write-Host "4 Tags Keys [$($AnalysisServicesServer.Tag.Keys)]"               # Show keys
    Write-Host "5 Tags Keys [$($AnalysisServicesServer.Tag.Keys["Environment"])]" # NOT WORKING
}

因此Tag属性是哈希表。有多种方法可以访问哈希表的值，但是我会使用你已经尝试过的那个，但只是语法有点错误。以下是我将如何完成您正在寻找的内容。

$AnalysisServicesServers = Get-AzureRmAnalysisServicesServer | Where-Object {$_.Tag['Environment'] -ne "Production"}

如果你的结果没有“环境”，那么这可能会引发错误。标记在他们身上，但它会为您提供您正在寻找的结果。
