Powershell - Remove from Json - json

Question

I have the following Json file:
{
"Id":1,
"Name":"john",
"Addresses":[
{
"Id":1,
"Street":"1st Street",
"City":"Riyadh"
},
{
"Id":2,
"Street":"2nd Street",
"City":"Dammam"
}
]
}
I want to remove the second address in the array using powershell.
I tried the following:
$filePath = 'C:\temp\Settings.json'
$settings = $filePath | ConvertFrom-Json
foreach($item in $settings.Addresses)
{
if($item.Id -eq 2)
{
$settings.Addresses.Remove($item)
}
}
Any ideas?

Answer 1

The following commented code snippet could help:
$filePath = 'C:\temp\Settings.json'
$settings = Get-Content -Path $filePath | ConvertFrom-Json
# $settings.Addresses # is an array of fixed size
# $settings.Addresses.IsFixedSize # returns True
# $settings.Addresses.Remove($item) # isn't possible; hence, let's build new array:
$NewAddresses = [System.Collections.ArrayList]::new()
foreach($item in $settings.Addresses)
{
if ($item.Id -ne 2)
{
[void]$NewAddresses.Add( $item )
}
}
# and replace old one:
$settings.Addresses = $NewAddresses
$settings | ConvertTo-Json ### | Out-File -FilePath $filePath -Force -Encoding utf8

{
"Id": 1,
"Name": "john",
"Addresses": [
{
"Id": 1,
"Street": "1st Street",
"City": "Riyadh"
}
]
