Write script to search the solution - visual-studio

Question

I'm working on removing a large number of old and unused images from our website. We run ASP.NET with C# code behind, and do our work out of Visual Studio (2013). Right now I'm just going through our images directory and searching the solution for the image file name. While we have some filenames that follow a pattern and can be done in a group using regex, this is still rather tedious. Is there a way that I can write a batch script (or anything) to search the solution for every file in this directory? I can imagine pseudocode like
for file in images_directory
if file not in solution
delete file
but is this possible?
Technically we're just moving the files into another folder to be safe, so I guess the actual pseudocode would be more like
for file in images_directory
if file not in solution
move file to backup_directory

Within your solution file, find all references to .csproj files. Within each .csproj file, find all include lines. Within each included file, find all lines containing references to images. Copy each relevant line to a temporary list. This will make searching faster than searching every .cs file multiple times for every image.
For each graphic file, use findstr to perform a regexp search for /\bfilename\b/i within the temporary list. If not found, use conditional execution to initiate a move of the orphaned image to backup.
Save this with a .bat extension, modify the first three set lines to appropriate values, and give it a shot. By default, it only pretends to move. If you're satisfied that the simulations will produce correct results, remove echo from the move line near the bottom to let the script off its leash.
#echo off
setlocal
set "image_dir=c:\path\to\images"
set "sln_file=c:\path\to\solution\Project1.sln"
set "backup_dir=c:\path\to\backup"
set "remember=%temp%\proj_images.txt"
for %%I in ("%sln_file%") do pushd "%%~dpI"
rem // .sln -> .csproj -> .cs -> images. Find image references and remember.
del "%remember%" >NUL 2>NUL
for /f "delims=" %%I in ('findstr /i ".csproj\>" "%sln_file%"') do (
rem // %%I contains lines matching /.csproj\b/ig
for %%p in (%%I) do if exist "%%~p" (
rem // %%p contains a .csproj filename
for /f "delims=" %%J in ('findstr /i "\<include\>" "%%~p"') do (
rem // %%J contains lines matching /\binclude\b/ig
for %%c in (%%J) do if exist "%%~c" (
rem // %%c contains the filename of an include
findstr /i ".png\> .jpg\> .gif\> .bmp\> .tif\>" "%%~c" >>"%remember%" && (
echo Images referenced within %%~nxc. I'll remember this.
)
)
)
)
)
rem // for each image file in image_dir (recursive)
for /r "%image_dir%" %%I in (*.png *.jpg *.gif *.bmp *.tif) do (
rem // regexp test for /\bfilename.ext\b/i
findstr /i "\<%%~nxI\>" "%remember%" >NUL || (
rem // non-zero exit status of findstr means not found
echo %%~nxI is not referenced by any files included in the solution's projects.
rem // *********************************************************
rem // REMOVE "ECHO" FROM THE FOLLOWING LINE TO ENABLE THE MOVES
rem // *********************************************************
echo move "%%~fI" "%backup_dir%"
)
)
del "%remember%" >NUL 2>NUL
echo Press any key to exit.
pause >NUL
Is this what you had in mind?

All together If I understand correctly You first want to obtain all images files from directory. Using PowerShell:
$imageFiles = Get-ChildItem 'path/to/image/directory' -Recurse | Where-Object { !($_.PSIsContainer) }
This grabs all files excluding Directories. Then:
$solutionText = Get-Content 'path/to/solution/file.csproj' | Out-String
ForEach ($file in $imageFiles ) {
if ($solutionText -match $file.Name) {
# Move to another folder
}
}
The only issue is that you'd need to make sure that the filenames don't have a chance of matching elsewhere on the file giving false positives.
