In my c# application
when i use this FileStream fs = File.Open("C:\\Temp\\497_01\\\
\Assumption.txt",FileMode.Open);

1. it works fine, when i ran the exe locally. (e.i : c:\> c\temp
\Test.exe)

2. When i execute the exe from share path it throw an exception saying
file does not exists
(e.i :C:\> \\TTTYUOT\temp\Test.exe)

Can any one suggest what could be the reason?


thanks

Hi,

Can you add more code sample? I still can't get the connection between
the FileStream and the exception.

Hi Moty,

The problem is with this line only
File.Open("C:\\Temp\\497_01\\\\Assumption.txt",FileMode.Open);

the extra "\\" between present in the file path "497_01\\\
\Assumption".

it runs fine when i execute the code locally but throws exception file
not found when i ran it through network share like :C:\> \\TTTYUOT\temp
\Test.exe)


thanks

First one hint. For file path it's better to use verbatim strings:
.... @"C:\Temp\497_01\\Asumption.txt" ...
this is much easier to read.

This puzzles me. I couldn't even construct such path.
What Filesystem you are using.

The extra slash seems to have an effect like a relative path.
Where is the file actually located ?

The file is located at C:\Temp\497_01\Assumption.txtI understand the the path is not correct but it works in local mode
but not in network mode (i.e C:\> \\TTTYUOT\temp\Test.exe)
 
The .Net permissions are different when you run the executable locally
than when you run it from a share path. The default permissions of a .Net
executabe loaded from a share path do not allow you to perform file IO
operations. You can chage those permissions from the .Net administration
tool in the control panel.

So, why you don't simply remove the extra slash?

Thanks so much it was a .Net security/permissions issue its is fixed
after adding File IO. to the Zone
