求助：在PowerShell中使用HJSON C#库的操作问题

Let’s work through getting the HJSON C# library running smoothly in PowerShell, starting with verifying your setup, fixing common pain points, and walking through practical examples aligned with the library’s functionality.

1. First: Verify Assembly Loading #

Before diving into HJSON operations, confirm your DLL is loading correctly—path mismatches or architecture conflicts (32-bit vs 64-bit) are common culprits here. Add this validation step to your script:

$scriptRoot = Split-Path $script:psEditor.GetEditorContext().CurrentFile.Path
$filePath = (Get-Item .\Hjson.dll).FullName

# Load assembly with error handling
try {
    $assembly = [System.Reflection.Assembly]::LoadFrom($filePath)
    Write-Host "Successfully loaded assembly: $($assembly.FullName)"
}
catch {
    Write-Error "Failed to load Hjson.dll: $_"
    exit
}

2. Correct Usage of HJSON Methods #

The [Hjson.hjson] class has specific method overloads—let’s adjust your code to work reliably and convert HJSON content into PowerShell-friendly objects for easier manipulation.

Example: Load & Parse an HJSON File #

try {
    # Load the HJSON file into an HJSON object
    $hjsonObject = [Hjson.hjson]::Load("$scriptRoot\test.hjson")
    
    # Convert the HJSON object to a JSON string, then to a PowerShell PSObject
    $jsonString = [Hjson.hjson]::ToString($hjsonObject)
    $psObject = ConvertFrom-Json $jsonString
    
    Write-Host "Loaded HJSON content:"
    $psObject | Format-List
}
catch {
    Write-Error "Failed to process HJSON file: $_"
}

Example: Create & Save HJSON Content #

If you need to generate HJSON files, here’s a straightforward workflow:

# Create a sample PowerShell object
$appConfig = @{
    AppName = "MyTool"
    Version = "2.1.0"
    Features = @{
        DarkMode = $true
        AutoUpdate = $false
    }
}

# Convert to JSON, then parse into an HJSON object
$jsonString = $appConfig | ConvertTo-Json
$hjsonObject = [Hjson.hjson]::Parse($jsonString)

# Save to a new HJSON file
[Hjson.hjson]::Save("$scriptRoot\config.hjson", $hjsonObject)
Write-Host "HJSON config file saved successfully."

3. Fix Common Issues #

• Architecture Mismatch: If your DLL is compiled for x64 but you’re running 32-bit PowerShell (or vice versa), the assembly won’t load. Check your PowerShell architecture with [Environment]::Is64BitProcess and recompile the DLL to match.
• Missing Dependencies: The HJSON-CS library may rely on other .NET assemblies. Check the original C# project’s dependencies and ensure those DLLs are in the same folder as Hjson.dll.
• Constructor Errors: [Hjson.IJsonReader]::new() might require parameters depending on the library version. Check the library’s source code for the correct constructor signature (e.g., passing a stream or string reader).
