Azure PowerShell数组对象转哈希表及输出异常问题求助

Hey there! Let's figure out why your hash table conversion is throwing that weird output and get your script working properly.

First, let's clear up a common mix-up with the Get-AzureRmTag cmdlet: when you run Get-AzureRmTag -Name $Environment -Detailed, you're getting metadata about the tag itself (like how many resources use it, and a list of associated resource IDs) — not the actual resource objects you need to pull version numbers from. That's part of why your hash table is ending up with unexpected content.

Second, your ForEach-Object logic has a syntax issue: $inputobject.$_ isn't how you reference properties of the current item in the pipeline. Inside ForEach-Object, you should use $_ (or $PSItem) to refer to the current object being processed.

Let's fix this step by step:

Step 1: Get the right resources #

Instead of fetching tag metadata first, directly get all resources that have your target tag using Get-AzureRmResource. This gives you the actual resource objects you need to extract version info from:

# Initialize an empty hash table
$SiteList = @{}

# Replace $EnvValue with the actual value of your Environment tag (e.g., "Production")
$taggedResources = Get-AzureRmResource -Tag @{ Environment = $EnvValue }

Step 2: Build your hash table correctly #

Now loop through each resource, pull the site name (or whatever key you want) and its version number. I'm assuming your version is stored in a tag called Version — adjust this to match where your version data lives (could be a resource property too):

$taggedResources | ForEach-Object {
    # Check if the Version tag exists to avoid null entries
    if ($_.Tags.ContainsKey('Version')) {
        # Use the resource name as the hash table key, version as the value
        $SiteList[$_.Name] = $_.Tags['Version']
    } else {
        # Optional: Handle resources missing the Version tag
        $SiteList[$_.Name] = "No version tag found"
    }
}

Step 3: Output the hash table properly #

Now when you call $SiteList, it should display your key-value pairs correctly. If you want a cleaner formatted view, use:

$SiteList | Format-Table -AutoSize

If you do need to use Get-AzureRmTag first #

If you specifically need to start with tag details (e.g., you only have the tag key and need to get all associated resources), you can do this instead:

$SiteList = @{}
$tagDetails = Get-AzureRmTag -Name $Environment -Detailed

# Loop through each resource ID linked to the tag
$tagDetails.Properties.Resources | ForEach-Object {
    $resource = Get-AzureRmResource -ResourceId $_
    if ($resource.Tags.ContainsKey('Version')) {
        $SiteList[$resource.Name] = $resource.Tags['Version']
    }
}

$SiteList

The main issues in your original code were:

• Using Get-AzureRmTag when you needed resource objects instead of tag metadata
• Incorrectly referencing $inputobject.$_ instead of using $_ to access the current item's properties

Give these adjustments a try and your hash table should output correctly!
