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 = (Get-Content $csproj)
$files_from_csproj = $xml.project.itemgroup | 
	%{ $_.Compile } | 
	%{ $_.Include } |
	?{ $_ } | 
	%{ Join-Path $dir $_ } |

# get the files from the dir
$files_from_dir = Get-ChildItem $dir -Recurse -Filter *.cs |
	%{ $_.FullName } |
Compare-Object $files_from_csproj $files_from_dir

    If you’re using TFS, there’s also the TFPT Treeclean command which will do the same for an entire workspace.

    This isn’t about finding files laying on disk that aren’t in source control.  For each of the files I found with this, they were in source control fine, but weren’t in any csproj files.  Since they weren’t actually being included in any projects, they were useless, so I went through each and "tf delete"-ed it, rebuilt to confirm, then checked in.
