Powershell脚本附加到JSON数组

Question

我正在努力使用PowerShell脚本向现有的JSON数组添加新元素。这是我的JSON文件结构。

[
  {
    "Company": [
      {
        "Finance": [
          {
            "StaffName": "Name1",
            "StaffRating": "Rating1"
          }
        ],
        "HR": [
          {
            "StaffName": "Name1",
            "StaffRating": "Rating1"
          },
          {
            "StaffName": "Name2",
            "StaffRating": "Rating2"
          }
        ]
      }
    ]
  }
]

我试图将以下对象附加到“公司” - >“HR”部分：

{
            "StaffName": "Name3",
            "StaffRating": "Rating3"
}

我尝试使用'+ ='没有运气。此代码不起作用，因为它从文件中删除内容而不会抛出任何错误：

    $FromJSON =  Get-Content  $JsonfilePath -raw  | ConvertFrom-Json
    $versionDataFromJSON.Company.HR += [pscustomobject] @{ StaffName= 'Name3'},[pscustomobject] @{ StaffRating= 'Rating3' }

    $FromJSON | ConvertTo-Json  | Set-Content $JsonfilePath

这是我想要的JSON：

[
  {
    "Company": [
      {
        "Finance": [
          {
            "StaffName": "Name1",
            "StaffRating": "Rating1"
          }
        ],
        "HR": [
          {
            "StaffName": "Name1",
            "StaffRating": "Rating1"
          },
          {
            "StaffName": "Name2",
            "StaffRating": "Rating2"
          },

           { "StaffName": "Name3",
            "StaffRating": "Rating3"
          }
        ]
      }
    ]
  }
]

这样怎么样......

$JsonDataAdd = @"
{
            "StaffName": "Name3",
            "StaffRating": "Rating3"
}
"@

$JsonData = @"
[
  {
    "Company": [
      {
        "Finance": [
          {
            "StaffName": "Name1",
            "StaffRating": "Rating1"
          }
        ],
        "HR": [
          {
            "StaffName": "Name1",
            "StaffRating": "Rating1"
          },
          {
            "StaffName": "Name2",
            "StaffRating": "Rating2"
          }
