Hey im using serialization to serialize my objects to hard drive,
reading them is no problem but overwriting them causes me problems,i
have un authorized access to the files but i gave the folder all the
permissions.

source:
http://www.vkarlsen.no/pastebin/default.asp?id=5545

can someone tell me what im not doing right
 
this only occurs when i write a new file and then try to over write it.
if the thread finishes and starts overagain i am able to overwrite a
file that already exists as often as i want..

Please post the exact exception message.
You should also post the complete code that illustrates the problem you
have, not a few methods like you did now.

Are you using a filestream to write to disk? Is it in a using block /
being cleaned up manually? The example below does not error. Remove the
'using' block, and you get a file locked exception:

"An unhandled exception of type 'System.IO.IOException' occurred in
mscorlib.dll

Additional information: The process cannot access the file "I:\x.dat"
because it is being used by another process."

static void Main(string[] args)
{
WriteFile();
WriteFile();
Console.Read();
}
static void WriteFile()
{
Foo foo = new Foo();
BinaryFormatter bf = new BinaryFormatter();
using(FileStream fs = new FileStream(@"I:\x.dat",FileMode.Create))
{
bf.Serialize(fs,foo);
}
}
 
Additional information: The process cannot access the file "I:\x.dat"
because it is being used by another process."

is the exact error im getting this is all on a webservice, and i am
using the user statment "block" and i still get this error when i
create a new fresh file where i overwrite the file im alright.

it seems that when i create a new filei have to wait for the gc to
dispose of the application thread to release everything before i can
overwrite....

i find this quite strange because the code is clean and should work i
juste cannot find anything wrong with it.

if any one can give me some light on this i would be greatful...

I think you need to post the code.
 
i am using this code in a web service, therefore i truely have no idea
why it causes this problem like you have experienced this code works
great locally
 
If you are trying to write to a file from a webservice you may have threading
issues as multiple requests would be trying to write to the same file.
