PowerShell JSON Deserializer

UPDATED WIKI: Home

dfinke — Wed, 20 Jun 2007 00:34:08 GMT

Project Description

This project contains three approaches to deserializing JSON formatted data into PowerShell Objects.

A PowerShell script
The PowerShell script converted to C# and compiled as a managed DLL
The managed DLL implemented as a PowerShell SnapIn

The Script

Place the script in a directory which is in your path

Managed DLL

The managed code stand alone version needs to load the dll with [reflection.assembly]::LoadFrom("") for each session

[void] [reflection.assembly]::loadfrom("$pwd\bin\debug\PowerShellJSONParser.dll")

The SnapIn

The snapin needs to be registered. This is only required once.

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe $pwd\bin\Debug\PowerShellJSONParser.dll

But the snapin must be added each session.

Add-PSSnapin ConvertFromJSONSnapIn

This can be simplfied by using the Export-Console Cmdlet.

Export-Console ConvertFromJSON

Performance

The PowerShell script is the slowest but easiest to modify.
The managed code requires re-compiliation.

Examples

The examples are the same for each implementation.

PS C:\> '[{"title":"PowerShell"},{"title":"Test"}]' | Convert-FromJSON | Invoke-Expression
