Problem in renaming CSV file after hosting ASP.NET application

[Rashmi_Karnam]

Hi, I have a Fileupload control, from where i am uploading CSV file and reading data from it and displaying in a gridview. If data is incorrect i am editting in GrdiView and click on Finish button. On click of finish button i am writing updated value back to CSV file from Gridview. This functionality i have implemented, but after hosting this application in IIS, when i access it in same system its rewriting to CSV file and renaming the file also. But if i browse hosted application in some other system and if i upload a file which is on browser system, its not renaming a file and not updating it. So please can any one help me what are the permissions i need to set in IIS or to file i am access, so that i can rename and update that file. I have checked following possiblities already 1. create ASPNET account and grant full permission for read, write.... 2. In IIS gave Anonymous access to user. 3. Checked with Impersonate option in web.config file. 4. Gave permissions to CSV file like read, write .... Code ----- writing to CSV File ------------------- StreamWriter sw = new StreamWriter(localsavedFilePath) foreach (DataRow row in dtCSV.Rows) { sw.Write("\"" + row[0].ToString() + "\""); sw.Write(sw.NewLine); }sw.Close(); File.Copy(localsavedFilePath, OriginalFileUploadedPath, true); Renaming File -------------- File.Move(OriginalFileUploadedPath, OriginalFileRenamedPath);

Check the identity that runs the application pool process. Give that account full control to the directory where you are writing the file. Also, here is a tip. Instead of using a StreamWriter, use a StringBuilder to build your .csv then use System.IO.File.WriteAllText.

I didn't get any requirements for the signature

Hi, Thanks for the reply... I tried what ever you have suggested, still renaming issue exist. i used string builder to build CSV file and used File.WriteAllText. It works fine only when i run application using Visual Studio and on which ever system i host the application. Except these two systems on all other system its not working. Please help me.... We need to deliver the project but due to renaming issue stuck up...

I wont get any exception. When i click on Finish button in my screen, i am interacting with DataBase and at last saving the CSV file and changing the name of the file. It wont throw any exception as its working fine in local system using VS2008 application and also when i host the application in my system itself. But if any one browse same application on different system, all Database activities are working fine and even all the code written for renaming CSV file will get executed but it wont rename the file. :((
