PowerShell 2.0 ConvertFrom-Json 和 ConvertTo-Json 实现 [英] PowerShell 2.0 ConvertFrom-Json and ConvertTo-Json implementation

问题描述

我想对目前无法升级到 3.0 的 PowerShell 2.0 环境进行猴子补丁.

I would like to monkeypatch a PowerShell 2.0 environment where the upgrade to 3.0 is not possible at this time.

我正在寻找 PowerShell 3.0 中 ConvertFrom-Json cmdlet 和 ConvertTo-Json cmdlet 的 PowerShell 2.0 脚本实现.

I am looking for a PowerShell 2.0 script implementation of the ConvertFrom-Json cmdlet and ConvertTo-Json cmdlet that are in PowerShell 3.0.

我对 ConvertFrom-Json 最感兴趣，但 ConvertTo-Json 也不错.

I am most interested in the ConvertFrom-Json, but ConvertTo-Json would also be nice.

推荐答案

function ConvertTo-Json20([object] $item){
    add-type -assembly system.web.extensions
    $ps_js=new-object system.web.script.serialization.javascriptSerializer
    return $ps_js.Serialize($item)
}

function ConvertFrom-Json20([object] $item){ 
    add-type -assembly system.web.extensions
    $ps_js=new-object system.web.script.serialization.javascriptSerializer

    #The comma operator is the array construction operator in PowerShell
    return ,$ps_js.DeserializeObject($item)
}

如果您收到错误:

Add-Type : Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 or one of its dependencies. The system cannot find the file specified. "

... 可以运行这些注册表命令(更多详情):
