Cannot delete a file (File being used by another process) * Resolved *

[MarkusJ_NZ]

Hi, I have a web application that spits out the following error when I try and delete a file from a code-behind page.

"The process cannot access the file c:\path\blah.jpg" because it is being used by another process"

If I wait a little while and try agiain then I can successfully delete the file from the exact same page.

I have declared everything referencing the file to nothing but I still can't delete the file without waiting a few minutes

Help appreciated

Cheers

=============

The following is a subset of the code that I was having problems with. It was fixed by adding in

fileGetImage.Dispose()
fileGetImage = Nothing
System.GC.Collect

HTH anyone who has a similiar problem
Cheers

Protected WithEvents fileGetImage As System.Web.UI.HtmlControls.HtmlInputFile
 
if page.isPostback then
fileGetImage.PostedFile.SaveAs("c:\imagename.jpg")
fileGetImage.Dispose()
fileGetImage = Nothing
' Call the garbage collection
System.GC.Collect
end if
 
' You can now delete the image
System.IO.File.delete("c:\imagename.jpg")

I have the exact same problem and haven't been able to find a solution. Did you resolve this issue?

Maybe forcing a garbage collection would solve this. I have also came across this problem, but found ways around it. I never tried garbage collection though, so who knows.

If you get it working, please post back what works.

I encountered this problem when I create a file and delete it soon after. If I create the file using File.Create() or FileInfo.Create() I get the error when I delete the file that is created. If I create the file using the following code, I don't get the error...

Dim fsUpdateFile As New FileStream(strFile, FileMode.OpenOrCreate)
fsUpdateFile.Flush()
fsUpdateFile.Close()

I don't know if it will help anyone else, but it seems to have solved my problems.
