Question

I have to compile multiple dlls (around 100) for my project.
Each project/build will have only one source code file different.
These dlls should have an index included. Like calc0023.dll

What is the easiest way to do that?

Answer 1

a .cmd script :

for %%f in (*.cs) do (
    csc.exe /target:dll /o:outdir\%%~nf.dll %%f CommonFile.cs 
)

If all the source files are in the same directory, you would have to exclude the common file from the loop.

for %%f in (*.cs) do (
    if not %%f==CommonFile.cs (
        csc.exe /target:dll /o:outdir\%%~nf.dll %%f CommonFile.cs 
    )
)

The previous scripts name the generated DLL with the name of the unique source file. If you want to use a numeric index for the filename, then you need to introduce another variable.

setlocal enabledelayedexpansion
set count=1
for %%f in ("*.cs") do (
    if not %%f==CommonFile.cs (
        set CSTR=00!COUNT!
        set OUTFILE=Calc!CSTR:~-3!
        csc.exe /target:dll /o:outdir\!OUTFILE!.dll %%f CommonFile.cs
        set /a COUNT=!COUNT!+1
    )
)
endlocal
