Subsequent Access To File. Error - The Process Cannot Access File It Is Being Used By Another
Mar 29, 2010
I simply want to create one file and then delete it, means I want to access one file subsequently. I am getting the very familiar error as shown in title. (Process can't access the file,) I have tried using file stream and all other stuff that I found from Googling but no success so far. Does any body have small and neat solution? in short, I would like to run the following statements without any error.File.Create("C:\hsp1.txt");
File.Open("C:\hsp1.txt", FileMode.Open, FileAccess.Read, FileShare.None);

I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:
FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read);
BinaryReader reader = new BinaryReader(fsr);
byte[] bytes = new byte[fsr.Length];
reader.Read(bytes, 0, bytes.Length);
FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write);
BinaryWriter writer = new BinaryWriter(fsw);
writer.Write(bytes, 0, bytes.Length);
// clean up
writer.Flush();
writer.Close();
writer = null;
fsw.Close();
fsw.Dispose();
fsw = null;
reader.Close();
reader = null;
fsr.Close();
fsr.Dispose();
fsr = null;
Later after sending the email I:
mailMessage.Dispose();
mailMessage = null;
foreach (string fileName in attachments)
{
if (File.Exists(fileName))
File.Delete(fileName);
}
The error occurs at: the File.Delete(fileName);
how I can delete or reopen these files after sending the email?

My code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?
here's the code:
protected void Page_Load(object sender, EventArgs e)
{if (!IsPostBack) // if this is the first time page loads, set k to 1
{ lognewuser();
}}

I am getting binary data from a SQL Server database field and am creating a document locally in a directory my application has permissions. However I am still getting the error specified in the title. I have tried numerous suggestions posted on the web including those suggested in previous posts on Stackoverflow. I have also used ProcessExplorer > Find Handle to locate the lock and it returns nothing as if the file is not locked.
I am using the code below to save the file to the file system and I then try to copy this file to a new location later in the application process within another method. It is this copy method that takes the path of the newly created file that throws the exception.
The file itself is created with its content and i can open it through Windows Explorer without any problems.
Am I missing something completely obvious? Am I creating the file correctly from the database?
// Get file from DB
FileStream fs = new FileStream(
"C:myTempDirectorymyFile.doc", FileMode.OpenOrCreate, FileAccess.Write);
BinaryWriter br = new BinaryWriter(fs);
br.Write("BinaryDataFromDB");
fs.Flush();
fs.Close();
fs.Dispose();
// Copy file
File.Copy(sourceFileName, destinationFilename, true);

I am using a AsyncUpload(telerik), i am in a point where i am supposed to save the File to a certain Folder. First I check if the directory exist
Code:
Dim baseDire As String = Server.MapPath("~/MyFILES/")
If IO.Directory.Exists(baseDire & Request("Req_ID").ToString()) = False Then
IO.Directory.CreateDirectory(baseDire & Request("Req_ID").ToString())
End If
Because i am doing multiple Upload , i will have to loop through the items of the Upload control and save to a folder.
Code:
For Each file As UploadedFile In UploadPropDoc.UploadedFiles
Dim bytes(file.ContentLength - 1) As Byte
file.InputStream.Read(bytes, 0, file.ContentLength)
'Save the File to the disk
file.SaveAs(baseDire + file.GetName())
Next
Now when ever i debug this , when it comes to this line
Code:
file.SaveAs(baseDire + file.GetName())
I get an Error
The process cannot access the file because it is being used by another process.
I have removed the Readonly in the Folder that it supposed to write to and gave everyone permission , but still the error persist.

whenever i m trying to upload more than one file i m getting this error "Cannot access a closed file. ". The file size is very small, the format is also .doc, .xls. The first file is uploaded correctly, no problem at all. The problem arise when system tries to write second file. Any ideas? On upload button event, I have taken all the files in httpfilecollection which i assign in session so that after attaching i can upload it later on save event. Problem occurs in save event that too on remote server. It's not happening on my local system.

I am getting "Access Denied" error when I am trying to write a file on my hard drive (C:/.... xmls/test.xml) from a webservice which is also on my local machine.
The folder structure is like this
AdminApp (Web Folder on C drive)
- WebServices Folder
- TestService.asmx
-Xmls Folder
- Test.xml
I tried following settings in IIS in my efforts to resolve the issue:
- Set anonynmous access checked with my account name and password under "Account Used for anonymous access" alongwith integrated windows authentication checked. I am a admin on my machine.
- Disabled anonymous access with only integrated windows authentication checked. I have identity impersonate = true set in my web.config.

I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)

I'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servernamefolder1folder2folder3foder4filename.pdf' is denied. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '......same as above....' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
