DirectoryInfo and FileInfo classes locking files

[David Turner]

I have created an ASP.NET page that uses the
System.IO.Direc toryInfo.GetFil es() method to get a list of files in a
specific directory on our web server. (I simply use this list to build some
javascript code). I'm never opening the files or accessing them in any
other way.

Problem is, that once this ASP.NET page is accessed, we can then no longer
delete or rename any of the files in that directory unless we restart IIS.

If I try and delete them using the System.IO.File. Delete() method I get the
following exception:

System.IOExcept ion
The process cannot access the file "..." because it is being used by another
process.

Any Ideas?

DirectoryInfo and FileInfo classes locking files

Hi

Strange. I tried this on my machine(running ASP.Net1.1)
and it workd fine. Im able to delete the files even after
the page is accessed!!!!

watch for linewraps

Dim l_objDirInfo As New DirectoryInfo
(TextBox1.Text)
Dim l_objFilesInfo( ) As FileInfo =
l_objDirInfo.Ge tFiles()
Dim l_objFileInfo As FileInfo
For Each l_objFileInfo In l_objFilesInfo
Response.Write( l_objFileInfo.N ame)
Next
l_objDirInfo = Nothing

Are u opening file handles elsewhere by mistake!!!

regards,

sr

Re: DirectoryInfo and FileInfo classes locking files

My bad!

The javascript that I was building actually referenced another aspx page for
each image, and I was using the image.fromfile method which was holding onto
the file. As soon as I switched to the image.fromstrea m method, things
started working great.
