Question

代码

我有以下脚本，主要基于此网站上的信息：

cls
if ($PSVersionTable.PSVersion.Major -lt 3) {
    function ConvertTo-Json([psobject] $item){
        [System.Reflection.Assembly]::LoadWithPartialName("System.Web.Extensions") | out-null
        $ser =  New-Object System.Web.Script.Serialization.JavaScriptSerializer 
        $hashed = @{}
        $item.psobject.properties | %{ $hashed.($_.Name) = $_.Value }
        write-output $ser.Serialize($hashed) 
    }
    function ConvertFrom-Json([string] $json){
        [System.Reflection.Assembly]::LoadWithPartialName("System.Web.Extensions") | out-null
        $ser = New-Object System.Web.Script.Serialization.JavaScriptSerializer
        write-output (new-object -type PSObject -property $ser.DeserializeObject($json))
    }
}

$jsonObj = (new-object -type psobject -property @{
    MyDummyData = @{
        Version = '1.0.4' 
        CreationDate = ("{0:yyyy-MM-ddTHH:mm:ss.fffZ}" -f ((Get-Date).ToUniversalTime())) 
        Demo = 'hello'
        Recurse = @{
            Hello = "hi"
            Greetings = @{
                what = "now"
            }
        }
    }
})

"`n`nobj"
$jsonObj 

"`n`nobj to json"
$jsonx = ConvertTo-Json($jsonObj)
$jsonx 

"`n`njson to obj"
$x = ConvertFrom-Json($jsonx)
$x 

"Compare"
$x -eq $jsonObj

输出

obj

MyDummyData
-----------
{Version, Demo, CreationDate, Recurse}


obj to json
{"MyDummyData":{"Version":"1.0.4","Demo":"hello","CreationDate":"2015-07-23T18:
59:04.265Z","Recurse":{"Greetings":{"what":"now"},"Hello":"hi"}}}


json to obj
{[Version, 1.0.4], [Demo, hello], [CreationDate, 2015-07-23T18:59:04.265Z], ...
Compare
False

问题

当我测试时ConvertTo-Json完美无缺。但是ConvertFrom-Json没有解析为我开始使用的对象，而是给了一个包含许多名称 - 值对的对象。

问题

任何人都可以发现我错过的东西;或者这里提出的方法是否仅适用于某些情况？

Powershell v2中的ConvertFrom-Json
