中的列表

Question

我正在尝试将以下JSON解析为PSCustomObject

[
  {
    "tags": [
      {
        "tagName": "Microsoft Teams"
      },
      {
        "tagName": "Worldwide (Standard Multi-Tenant)"
      },
      {
        "tagName": "General Availability"
      },
      {
        "tagName": "Web"
      },
      {
        "tagName": "Desktop"
      }
    ],
    "tagsContainer": {
      "products": [
        {
          "tagName": "Microsoft Teams"
        }
      ],
      "cloudInstances": [
        {
          "tagName": "Worldwide (Standard Multi-Tenant)"
        }
      ],
      "releasePhase": [
        {
          "tagName": "General Availability"
        }
      ],
      "platforms": [
        {
          "tagName": "Web"
        },
        {
          "tagName": "Desktop"
        }
      ]
    },
    "id": 51230,
    "title": "Microsoft Teams: New file sharing experience",
    "description": "Streamline sharing with Microsoft Teams. You can now create a shareable link for any file stored in Teams and directly set the appropriate permissions. Additionally, you can also set permissions for files stored in SharePoint or OneDrive while composing a private chat or starting a channel conversation.",
    "status": "Launched",
    "moreInfoLink": "https://techcommunity.microsoft.com/t5/microsoft-sharepoint-blog/rich-new-file-and-sharing-experiences-throughout-microsoft-365/ba-p/960129",
    "publicRoadmapStatus": "Include this month",
    "created": "2019-05-08T07:00:00",
    "modified": "2022-01-13T00:05:19.663",
    "publicDisclosureAvailabilityDate": "March CY2021",
    "publicPreviewDate": ""
  }
]

我将该JSON存储在这样的变量中：

$RoadmapContent = Get-Content -Raw -Path ".\M365Roadmap_single.json" | ConvertFrom-Json 

这就是我的PSCustomObject：

$RoadmapItems =[PSCustomObject]@{
        Title = $($RoadmapContent.title)
        Tags = $($RoadmapContent.tags)
}

我想把这个标签放在一个列中，比如:微软团队、全球(标准多租户)、通用可用性、Web、桌面

我曾试图这样做(但没有成功)：

$RoadmapContent.Tags -join ";"

我如何解析这个？

非常感谢！

编辑：

我可以访问这样的标签：

foreach ($tag in $RoadmapContent.tags) {Write-Host $Tag.tagName}

但不知道如何在PSCustomObject中使用它。

多亏了原问题中的一条评论，我们才弄明白了这一点，下面是完整的代码：

$RoadmapContent = Get-Content -Raw -Path ".\M365Roadmap_single.json" | ConvertFrom-Json 

$RoadmapItems =[PSCustomObject]@{
        Title = $($RoadmapContent.title)
        Tags = $($RoadmapContent.tags.tagname -join ', ')
}

$RoadmapItems
