I have a detailsview which uploads 4 files and uses the objectcontainerdatasource. However, what I would like to do is once I got my files from the fileupload object is to cast it to FileInfo type.At the moment I can get hold of the files via detailsview but this is where I need help; as I have four files to upload, I want to save them to either an array, collection or list of type FileUpload or FileInfo (preferably FileInfo) along with two other properties and then to pass these values to a method that saves these files to a temporary location. This brings me to my next problem. In the method that saves the files to a temporay location, whilst I can do this with FileUpload, I want to return from this method the new file path location as a FileInfo type in order to use this in another method.

so basically my method takes a FileInfo as a paramter, creates a nwe image, saves it and actually returns the FileInfo (no idea why - it doesn't really need to)
I want to delete the Fileinfo object (aka the file in the temp storage directory) after the image has been created but when i try to run fi.Delete() i get an error saying it can't because its being used by another process.
whats the solution to this? is it possible to delete this file in the same thread or am i going to have to create a service that runs on a schedule and cleans this folder.
What about creating a new fileinfo pointing to the current fileinfo and deleteing that?
