The file has been opened by another application, where it might still be in use, or by a previous run of your own application, and has not been closed properly. Contrary to some other systems, .NET does not automatically closes files, you need to explicitely do it yourself.

If it is opened in another application, then you have to close that application and hope that it will close the file properly.

Otherwise, you first need to reboot your computer to release the file.

Be sure to add a file.Close call before the end of your method. Also, be sure to catch all possible errors in a try...catch and Close the file if an error happens after the file has been opened.

Can you kill the process through the Task Manager (Ctrl-Alt-Del)?
