Hi,
I have a website sitting on a server (ServerA) with images to be
displayed sitting on a separate server (ServerB) on the same network.
I am trying to test for the existance of an image using:
File.Exists(Ser ver.Path("/images/" + "myImage.jp g")
where the folder "images" is the virtual folder where the images are
stored.
Server.Path ("/images/" + "myImage.jp g") returns, as expected, the path on
ServerB in the form: "\\ServerB\...\ Images\myImage. jpg"
However, although the image does exist and displays on the webpage, the
File.Exists returns False.
Am I doing something fundamentally wrong here?
Many thanks for any help.
Pete

Italian Pete,
You might wanna check with the Don about this.
It's not
File.Exists(Ser ver.Path("/images/" + "myImage.jp g")
It's
File.Exists(Ser ver.MapPath("/images/" + "myImage.jp g")

The funny thing about File.Exists is that it seems the original developer was
determined to return a bool and not an exception so it swallows some usefull
exceptions like security exceptions and just returns false. It can be usefull
to comment out that line of code and try to open the file with a file stream
or something, this may then throw some security exception and give you a real
error message to work on.

hi Pete,
Sorry, that was my typo, I did in fact mean Server.MapPath (which didn't
work).
any other ideas?

Yes,
aside from Ciaran's exellent comments, wrap your call in a try /catch block
anyway and output any exception message and stacktrace.

I have compiled some code, some written by me, some compiled from
various sources online, and basically i've got a very simple flat file
photo gallery. An upload form, to upload the photos and give them a
caption, storing the caption and filename in a text file. It's a bit
buggy when removing the photos and captions from the file, and also in
displaying them on the delete page. you can see it in action at

I have code like the following to test for existence of a file. I know the
file is there, but File.Exists returns FALSE. The problem appears to be
that the file is in a directory beneath "My Documents". When I move it to a
directory directly under the root, File.Exists returns TRUE. So I tried
using FileIOPermission to give me rights to read it, but still no luck. Any
suggestions? Thanks...

I am using the System.IO.File class to determine if a file exists on a
network share.
The File.Exists method keeps returning false, even though the file does
exist. The MSDN documentation states,
"If the caller does not have sufficient permissions to read the specified
file, no exception is thrown and the method returns false regardless of the
existence of path."

Hi,
I have a problem that I have been working with for a while.
I need to be able from server side (asp.net) to detect that the file i'm
streaming down to the client is saved completely/succsessfully on the
client's computer before updating some metadata on the server (file
downloaded date for instance)
However,
All examples i have tried, and all examples I have found that other people
says works - doesn't work for me :-(

Hi All,
I noticed if file path has a white space, for example "C:\my document
\test.txt", the function File.Exists(filePath) always return false in
release mode. How could I make this function work for the file which
is located in a direcotry with a white space?
Thanks!

Newbie question:
I'm trying to determine if a file physically exists regardless of the
permissions on it
Using File.Exists() returns false if it physically exists but the
process does not have the necessary permissions.
One hack could be to check for length and that would throw a
FileNotFoundException ...but there is got to be a better way!
