Can't pass through "" to powershell using ProcessStartInfo arguments, C#-CodePudding

I'm unable to pass through an argument to powershell which contains "". When I use the equivalent code but change the application to cmd the "" are able to pass through.

The argument I'd like powershell to execute is:

Copy-Item -Path "{Working Directory}\W11F-assets\" -Destination "C:\\Windows\W11F-assets" -Recurse

This is the code that's calling that function:

    ProcessStartInfo movefile = new ProcessStartInfo("powershell.exe");
    string flocation = Directory.GetCurrentDirectory();
    movefile.UseShellExecute = true;
    movefile.Arguments = "Copy-Item -Path \""   flocation   "\\W11F-assets\" -Destination \"C:\\Windows\\W11F-assets\" -Recurse";
    Process.Start(movefile);

When commands are passed to the PowerShell CLI's (positionally implied) -Command (-c) parameter, any unescaped " chars. are stripped during command-line processing, and only then are the arguments (space-joined to form a single string, if there are multiple ones) interpreted as PowerShell code.

Therefore:

" characters that are to be retained as part of the command(s) must be \"-escaped.
Additionally, to prevent potentially unwanted whitespace normalization (folding multiple adjacent spaces into one), it is best to enclose the command(s) in unescaped embedded "..." overall.

To fully spell out a solution that should work, with explicit use of -Command and also -NoProfile to avoid usually unnecessary loading of the profile files, and with extra spaces for conceptual clarity:

movefile.Arguments = 
  $@"-NoProfile -Command "" Copy-Item -Path \""{flocation}\W11F-assets\"" -Destination \""C:\Windows\W11F-assets\"" -Recurse "" ";

Was able to solve issue by replacing \" with '.
