Question

我有一个数组，其中包含一个包含数据的嵌套哈希表：

tid              : 1
token            : 12345
participant_info : @{firstname=bob; lastname=smith; email=bob.smith@email.com}
completed        : y

tid              : 2
token            : 67890
participant_info : @{firstname=Alice; lastname=Jones; email=alice.jones@email.com}
completed        : n

我想将此输出为CSV，其中第一个名称，姓氏和电子邮件的嵌套项目从内部哈希表中拉出 - 例如

tid,token,firstname,surname,email,completed
1,12345,bob,smith,bob.smith@email.com,y
2,67890,alice,jones,alice.jones@email.com,n

我猜测答案是循环使用foreach并创建一个自定义的ps对象，但由于我的嵌套项目没有命名，我无法弄清楚如何使用此处的其他示例执行此操作。

感谢任何帮助！谢谢！

鉴于你的样本：

private val searcher = Searcher.create(APP_ID, API_KEY, INDEX_OBJECT)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_search)

        setSupportActionBar(tbSearch)
        supportActionBar?.setHomeAsUpIndicator(R.drawable.ic_arrow_back_normal_48px)
        supportActionBar?.setDisplayHomeAsUpEnabled(true)

        window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE)
        val q = Query()
        q.filters = "id:Hj5RFIzLjk5XTJOdODeu"
        searcher.query = q
        val helper = InstantSearch(this, searcher)
        helper.search()
    }

期望的输出：

@(
    [pscustomobject]@{
        tid = 1
        token = 12345
        participant_info = @{
            firstname = 'bob'
            lastname = 'smith'
            email = 'bob.smith@email.com'
        }
        completed = 'N'
    }

    ...
)

您可以这样做：

id,token,firstname,surname,email,completed
1,12345,bob,smith,bob.smith@email.com,y
2,67890,alice,jones,alice.jones@email.com,n

编辑：您正在处理$JsonList = @( ... ) $Path = "$Env:UserProfile\file.csv" ForEach ($Sample in $JsonList) { $Sample | Select-Object -Property @( @{N = 'id'; E = { $Sample.tid }} @{N = 'token'; E = { $Sample.token }} @{N = 'firstname'; E = { $Sample.participant_info.firstname }} @{N = 'surname'; E = { $Sample.participant_info.lastname }} @{N = 'email'; E = { $Sample.participant_info.email }} @{N = 'completed'; E = { $Sample.completed }} ) | Export-Csv -Path $Path -Append }，而不是PSCustomObject，因此我之前的语法不适用于此。这就是我现在假设您的代码看起来像现在（我已经更新了上面的示例）：

Hashtable

将嵌套哈希表导出到powershell中的csv
