PowerShellでJSONファイルを読み込むサンプルコード(レコードのようなJSONファイル編)

powershell -ExecutionPolicy RemoteSigned -File "ReadJson_multi.ps1"

# JSONファイルの読み込み
$jsonContent = Get-Content -Path "json_multi.json" -Raw
$jsonObj = ConvertFrom-Json $jsonContent

# 繰り返し処理 1 
$jsonObj | ForEach-Object { Write-Host $_.id }

# 繰り返し処理 2
foreach($person in $jsonObj){
    Write-Host $person.name
}
