powershell script - find orphaned C# files
I ran across a C# file that had been removed from its csproj file, but it hadn't been deleted from version control. So I wrote a script (Chris Sidi had already written one, though) to find the .cs files that weren't in the "containing" .csproj file
param([string]$csproj = $(throw 'csproj file is required'))
$csproj = Resolve-Path $csproj
$dir = Split-Path $csproj
# get the files that are included in compilation
$xml = [xml](Get-Content $csproj)
$files_from_csproj = $xml.project.itemgroup |
%{ $_.Compile } |
%{ $_.Include } |
?{ $_ } |
%{ Join-Path $dir $_ } |
Sort-Object
# get the files from the dir
$files_from_dir = Get-ChildItem $dir -Recurse -Filter *.cs |
%{ $_.FullName } |
Sort-Object
Compare-Object $files_from_csproj $files_from_dir
