解决方案
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.您可能忘记在同一个应用程序中处理/关闭某些内容。所以，首先，检查一下。要探索这种可能性，请参阅我过去的答案：
清除C＃中的句柄 [ ^ ]。
在这个答案中，注意使用/ code>语句可以帮助您保证在使用后正确处理相应的文件系统对象，而不是保持文件锁定。
在同样的情况下，你真的需要调查哪个进程拥有哪个文件。为此，我建议使用 Sysinternals Suite 中的一个实用程序。这组实用程序（以前来自 Winternals 公司，目前在Microsoft）是必须的对于任何开发人员，请参阅：
http://technet.microsoft.com/en -us / sysinternals / bb842062 [ ^ ]，
http://technet.microsoft.com/en-us/sysinternals / bb545027 [ ^ ]。
您需要的实用程序是 handle.exe ，请参阅：
http://technet.microsoft.com/en-us/sysinternals/bb896655 [ ^ ]。
在您的情况下，您使用文件名参数：
handle.exe< file_name>
此实用程序将扫描所有类型的句柄，而不仅仅是文件句柄。对于文件，它将扫描与文件名匹配的所有文件句柄（因此它不必是完整路径名）并返回足以识别每个进程的信息，包括其 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,

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
Generating-PDF-using-ItextSharp-with-Footer-in-Csh
I am using iTextSharper but the output gets : The process cannot access the file ''C:\inetpub\wwwroot\wss\VirtualDirectories\80\Upload\KingSize_2013-04-29.pdf'' because it is being used by another process.

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 theusingstatement 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:

Good luck,

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
