This is easy to investigate.

First of all, the similar question was asked here many times, and from this experience I know: in most cases the blocking process is your own process. You could have forgotten to dispose/close something in the same application. So, first of all, check it up. To explore this possibility, please see my past answer:
Clearing a Handle in C#[^].

In this answer, pay attention for the using of the using statement which helps you to guarantee that appropriate file system object is properly disposed after use, not keeping the file locked.

In same cases, you really need to investigate which process holds which file. For this, I recommend using one utility from the Sysinternals Suite. This set of utilities (formerly from Winternals company, presently at Microsoft) is a must-have for any developer, please see:
http://technet.microsoft.com/en-us/sysinternals/bb842062[^],
http://technet.microsoft.com/en-us/sysinternals/bb545027[^].

The utility you need is "handle.exe", please see:
http://technet.microsoft.com/en-us/sysinternals/bb896655[^].

In your case, you use it with file name parameter:
handle.exe <file_name>


This utility will scan all kinds of handles, not just file handles. For file, it will scan all file handles matching the file name (so it does not have to be a full path name) and return information sufficient to identify each process, including its pid. So, if you need more information on a process in question, you can also use other Sysinternals utilities, in particular, its Process Explorer:
http://technet.microsoft.com/en-us/sysinternals/bb896653[^].

Good luck,
—SA

how should i now which one i should dispose?
i get the error on this line Response.TransmitFile(Server.MapPath("~/Upload/") + strFileName);
Kurac1 29-Apr-13 17:01pm    
i did like on this linke http://www.4guysfromrolla.com/articles/030911-1.aspx were do u se him use dispose(); ? i got it to work before when i hade less columns but then i added more and then i got the problem , dont now why... worked before..
Sergey Alexandrovich Kryukov 29-Apr-13 17:10pm    
Use handle.exe on the host reporting this problem; you will see what process holds the file handler...
Transmit file should dispose internally, this is not where you need to dispose anything; the file was left non-disposed elsewhere...

i have runned the program handlex.Exe it only run and nothing more what should i do '?
Sergey Alexandrovich Kryukov 29-Apr-13 17:37pm    
Not true. It always write some text on output. Did you use command line I've shown? It's hard to ask but... did you noticed this is a console application. Did you see the console? Do you know how?
—SA
thats because u are creating a filestream object but not closing it kindly use as below

FileStream file = new FileStream(stringPath);

and after closing your pdfDocument close your stream also

file.Close();

for ref you can use below link
