I have a Json which is similar to this sample here

{
"vaults": {
"43371adf": {
"path": "C:\Users\user23\Documents\Mango Vault",
"ts": 16767
},
"54a80cfadc691ec4": {
"path": "C:\Users\user23\Documents\Apple Vault",
"ts": 166576
},
"af524734": {
"path": "C:\Users\user23\Documents\Orange Vault",
"ts": 166985
},
"40290aab5": {
"path": "C:\Users\user23\Documents\Banana Vault",
"ts": 167293,
"open": true
}
},
"frame": "hidden"
}

I am interested in retrieving the values for the keys `Path`. Some things I tried are:

$vaultsIndex = Get-Content -Path "C:\Temp\sample.json" | ConvertFrom-Json
$vaultsIndex.vaults
$vaultsIndex.vaults | foreach {$_.where -eq 'path'} #Returns 'False'
$vaultsIndex.vaults.where -eq 'path' #Also Returns 'False'

The only thing that works is `$vaultsIndex.vaults.43371adf` which I cant automate at all, I really need to just be all to get all the paths in a generic way.

The searches I performed just pointed me to this `$_.where()` method. Any help would be greatly appreciated!

你可以通过调用[`.PSObject.Properties`](https://learn.microsoft.com/en-us/dotnet/api/system.management.automation.psobject.properties?view=powershellsdk-7.2.0)来访问对象的属性。由于你只对`vault`中每个对象的`path`感兴趣，我们可以调用属性集的[`.Value`属性](https://learn.microsoft.com/en-us/dotnet/api/system.management.automation.psmemberinfo.value?view=powershellsdk-7.2.0#system-management-automation-psmemberinfo-value)来访问它们，然后调用每个对象上的`.path`来获取值。这是通过[成员访问枚举](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_member-access_enumeration?view=powershell-7.2)来完成的：

```powershell
$json.vaults.PSObject.Properties.Value.path

$json.vaults.PSObject.Properties.Value.path
