code-conversion's Issues

FileNotFoundException when CodeConversion.exe provided with -o argument

Directly invoking the executable, since the script passes the wrong parameters as mentioned in #12, still doesn't work, throwing a FileNotFoundException for the output file:

CodeConversion.exe -i .\MyModule.psm1 -o .\MyModule.cs

results in:

Unhandled exception. System.IO.FileNotFoundException: Could not find file 'V:\MyModule.cs'.

ConvertTo-Powershell appears to use the wrong working path

Even though the prompt is at my home folder, it forces the working path to be c:\windows\system32.

PS C:\Users\Andrew.Stanton> ConvertTo-Powershell -CSharpFile .\source\repos\MochaResultTestRailUploader\MochaResultTestRailUploader\MochaTypes.cs
ConvertTo-PowerShell: File C:\WINDOWS\system32\source\repos\MochaResultTestRailUploader\MochaResultTestRailUploader\MochaTypes.cs not found.

If i give it the full path I get the error named in #1

Doesn't work for conversions from C# to PowerShell

Doesn't seem to work for converting to PowerShell. It can convert methods but does not handle classes with properties.

CodeConversion v2.0.1 throwing errors when converting from C# to Powershell

Hello, I am trying to convert a ~100 line C# snippet to Powershell so that I don't have to use Add-Type to call the code however CodeConversion is erroring out. Below is the error I get:

And here is a link to the gist of the C# code so that I don't have a 100 line code block in the issue:

Thanks for any assistance you can provide!

Incorrect parameter passing to executable from Invoke-CodeConversion

Invoke-CodeConversion -InputFile .\MyModule.psm1 -OutputFile MyModule.cs

The parameters the executable expects do not match.

The executable is expecting either -o or --OutputPath, but the script is explicitly sending --OutputFile.

But even directly invoking the executable with the correct parameters fails, which I'll post as another issue.

PowerShell > C# using 'File' parameter set fails (module v2.0.1)

When attempting to convert from PowerShell to C#, I'm running this:

$Params = @{
    InputFile  = "$env:SystemRoot\repo\Modules\test\classes\class_Options.ps1" 
    OutputFile =  "$env:SystemRoot\repo\Modules\test\classes\class_Options.cs"
}
Invoke-CodeConversion @Params

The CodeConverter outputs the below error. Curiously, the converter doesn't throw errors (i.e. it outputs to stdout instead of stderr), but I digress.

CodeConversion 1.0.0
Copyright (C) 2023 CodeConversion

ERROR(S):
  Option 'OutputFile' is unknown.
  Required option 'o, OutputPath' is missing.

  -i, --InputFile     Required. File to convert.

  -o, --OutputPath    Required. Output file.

  --PowerShell        Required. PowerShell script block to convert to C#

  --CSharp            Required. C# code to convert to PowerShell

  --help              Display this help screen.

  --version           Display version information.

I'm very inexperienced with .NET and C# (using this as a means to translate my PowerShell knowledge), but as best I can tell this is tracing to the Program.cs.

If I'm understanding it correctly, it's taking this line from /CodeConversion.psm1:

& $Path --InputFile $InputFile --OutputPath $OutputFile

which passes $OutputFile into the Options class in /src/Program.cs:

[Option('o', "OutputPath", Required = true, HelpText = "Output file.", SetName = "File")]
public string OutputFile { get; set; }

and somehow the $OutputFile parameter is not being passed correctly, causing a failure because the OutputPath option is required? If I'm understanding the context, the first error says the cmdlet is calling OutputFile as the option instead of OutputPath?

I'm not entirely sure if this is an actual bug or I am merely not using this correctly... But I'm also curious if I am correctly understanding the mechanics of this (testing my knowledge, if you will). Any help is appreciated.

Wrong output

input
Invoke-CodeConversion -CSharp 'namespace HelloWorld{class Hello { static void Main(string[] args){System.Console.WriteLine("Hello World!");}}}'

output

{
        param([string[]]$args)
        $System.Console.WriteLine($Hello)
}

CodeConversion does not work at all (in a Sandbox)

I started a fresh Sandbox and followed your instructions:

NuGet provider is required to continue
PowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories. The NuGet provider must be available in 'C:\Program Files\PackageManagement\ProviderAssemblies' or 'C:\Users\WDAGUtilityAccount\AppData\Local\PackageManagement\ProviderAssemblies'. You can also install the NuGet provider by running
'Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force'. Do you want PowerShellGet to install and import the NuGet provider now?

Unfortunately it didn't work at all. Am I doing something wrong or is this a bug?

Could not load file or assembly 'Microsoft.CodeAnalysis.CSharp,

Hello,

I am unable to use the ConvertTo-PowerShell command with the 'CSharpFile' parameter.
It returns an error ConvertTo-PowerShell: Could not load file or assembly 'Microsoft.CodeAnalysis.CSharp, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' - The specified file could not be found.

I think the DLL should be in the repo.

Thank you.

Cordially,

Thomas.
