c# - Delete file: The process cannot access the file -


i use mvc , have controller takes file name , deletes server, when use visual studio development server on local machine, page(controller) delete file on production server i'm getting following error:

the process cannot access file 'filename' because being used process  system.io.file.delete(server.mappath("~/content/myfolder/" + id));

before line of code custom request validation dont access file. file has been saved page right before page.

in fact want know process may accessing file. , if code previous pages(controllers) may cause problem? have searched found nothing useful.

you check identity under application pool of application runs, check permissions account. check process locked file, try this link.
