powershell [System.IO.File]::WriteAllLines not working-CodePudding

What's wrong with these PowerShell Commands. its doesn't write the file "test.txt"

PS> $stuff = @("AAA`n", "BBB`n")
PS> [System.IO.File]::WriteAllLines(".\test.txt", $stuff)
PS> dir
# Nothing here....

Is there anything misconfigured on my Computer that could cause this? Do I need to somehow reinstall .net?

CodePudding user response：

Try dir ~\test.txt - or use an absolute path c:\path\to\my\test.txt. Better yet look at the Set-Content cmdlet.

FYI: theres nothing wrong with your computer - your using a dotnet library so you need to be more specific (basically). Set-Content is the powershell way of doing this (and .\test.txt would work as your were expecting).

CodePudding user response：

.Net doesn't use the same path as your PowerShell. The solution is to resolve a relative path into a fullpath:

PS C:\> $stuff = @("AA", "BB")
PS C:\> $out_file = ".\out.txt"
PS C:\> New-Item -Force -Path $out_file
PS C:\> $out_full = $(Resolve-Path -Path $out_file)
PS C:\>[System.IO.File]::WriteAllLines(` 
    ".\testing.txt", $out_full)
