获取从select-object返回的单个元素到json字符串数组

# 假设我们有一个对象数组，对象包含name和age属性
$objects = @(
    [PSCustomObject]@{name = "John"; age = 25},
    [PSCustomObject]@{name = "Jane"; age = 30}
)

# 选择单个元素并将其转换为JSON字符串
$singleElement = $objects | Select-Object -First 1
$singleElementJson = $singleElement | ConvertTo-Json

# 获取多个元素并将它们组合成JSON字符串数组
$elements = $objects | Select-Object
$jsonArray = foreach ($element in $elements) {
    $element | ConvertTo-Json
}

# 打印结果
Write-Host "Single Element JSON: $singleElementJson"
Write-Host "JSON Array: $jsonArray"
