Hello,

I am developping an app with ASP .NET, and C# and I have a problem :

My app creates a temporary file, and when I need to erase this file, I
get an error message about this file beeing used by another process, so
i am unable to erase it.

Is there a solution for me to free this file from IIS and then erase it
properly ?

Thank you for your help.

Stop the aspnet_wp.exe process and then try it. Also, make sure that in
your app, you are closing the file properly, so it does not become locked.

Thank you, but my concern is about deleting this file from my app, when
I do not need it anymore, so I cannot stop aspnet_wp.exe process each
time I have to delete a file
(BTW, this file is just a JPG temporary file created by my app, not a
system or DLL file created by ASP or IIS)

One approach is to use the static GetTempFile property of the path object.
It returns a temporary path which may be used to write temporary files.
Temporary files are cleaned up on application restarts or server reboots so
if your delete code fails, the file eventually gets cleaned up. This
approach is also thread safe and scalable.

Surely if the file handle has been released then you should be able to
delete the file programmatically?

Are calling the Close\Dispose on the correct objects if you are manipulating
the file using the System.IO namespace, ideally you should be using the
'using' keyword.
